Description

Technical Field

[0001] This invention relates to the field of device communication technology, and in particular to a device communication method, system, terminal, and computer-readable storage medium based on a restricted message transmission protocol. Background Technology

[0002] With the rapid development of IoT technology, an increasing number of resource-constrained devices (such as wearable devices and smart home devices) need to connect to networks and communicate efficiently. These resource-constrained devices typically have limited computing power, storage space, and battery capacity, placing special demands on the lightweight, low-power, and high-efficiency nature of communication protocols. Currently, the mainstream communication protocol for resource-constrained devices is CoAP (Constrained Application Protocol, an application layer protocol specifically designed for IoT devices and resource-constrained networks). CoAP supports UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) transmission, provides optional reliability mechanisms, and supports asynchronous message exchange and simple caching. Its message structure includes a 4-byte fixed header and a variable-length options field, supporting various request methods and a rich response code system.

[0003] However, for communication between resource-constrained devices, such as deploying temperature sensors throughout a production line, each temperature sensor needs to periodically (e.g., every minute) collect and report current temperature data, while also supporting remote commands to dynamically adjust the reporting frequency to balance monitoring accuracy and system load. Existing technologies achieve this by using the CoAP protocol, but such scenarios impose special requirements on the communication protocol, and existing methods have the following shortcomings: (1) Excessive protocol overhead: For simple scenarios where only one byte of data is transmitted per minute (e.g., temperature and monitoring area number), the existing method has an excessively high header overhead, which reduces communication efficiency. In simple scenarios of device data reporting and command issuance, there is functional redundancy, which increases resource consumption. (2) High parsing complexity: The abstract layering and variable-length fields in the existing method result in high parsing complexity, and the data parsing process places higher demands on the CPU and memory resources of the low-power microcontroller, leading to increased processing latency; (3) Low security: The existing method only provides simple duplicate detection. Its complete security relies entirely on DTLS (Datagram Transport Layer Security), and the DTLS handshake process requires a lot of computing resources and network bandwidth.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0029] For communication between resource-constrained devices, such as deploying temperature sensors throughout a production line, each temperature sensor needs to periodically (e.g., every minute) collect and report current temperature data, while supporting remote commands to dynamically adjust the reporting frequency to balance monitoring accuracy and system load; existing technologies use the CoAP protocol for this purpose, but such scenarios impose special requirements on the communication protocol, and existing methods have the following shortcomings: (1) Excessive protocol overhead: The CoAP protocol's message header is fixed at 4 bytes, but its real complexity lies in its variable parts. The corresponding token and option fields use a type-length-value encoding method, and the option number uses incremental encoding, which increases the computational burden of parsing. For simple scenarios where only one byte of data is transmitted per minute (e.g., temperature and monitoring area number), the existing method has an excessively high proportion of header overhead in the CoAP protocol, which reduces communication efficiency. In simple scenarios of device data reporting and command issuance, there is functional redundancy, which increases resource consumption. (2) High parsing complexity: The abstract layering and variable-length fields in the existing method result in high parsing complexity, and the data parsing process places higher demands on the CPU and memory resources of the low-power microcontroller, leading to increased processing latency; (3) Low security: The existing method only provides simple duplicate detection. Its complete security relies entirely on DTLS (Datagram Transport Layer Security), and the DTLS handshake process requires a lot of computing resources and network bandwidth.

[0030] Therefore, this invention proposes a device communication method based on a restricted message transmission protocol to overcome the problems of excessive protocol overhead, high parsing complexity, and low security in existing technologies for communication between resource-constrained devices.

[0032] Specifically, in this embodiment of the invention, the invention is illustrated by adding temperature sensors to the entire production line to facilitate communication between resource-constrained devices that report the current temperature every minute. First, task requests are detected in real time using pre-set task detection instructions. When a user sends a device communication request (e.g., a request to query the current specific temperature), the user's device communication request is obtained. Then, for security purposes, to prevent risks associated with the device communication request, a security authentication is performed on the request, and the corresponding device communication task is obtained based on the authentication result. Second, a multi-dimensional task analysis architecture is constructed, and the device communication task is analyzed in depth based on this architecture to obtain task analysis results. Finally, the task analysis results are used to determine whether the device communication task is for resource-constrained devices.

[0043] Step S133: Obtain the task analysis result based on the first analysis result, the second analysis result, and the third analysis result.

[0044] Specifically, step S133 is implemented as follows: After obtaining the first analysis result, the second analysis result, and the third analysis result, the task analysis result is obtained based on the computational overhead analysis result, storage demand resource analysis result, network demand resource analysis result, and energy consumption analysis result of the first analysis result, the task latency analysis result and periodic characteristic analysis result of the second analysis result, and the data flow analysis result and protocol stack depth analysis result of the third analysis result.

[0045] Step S14: Determine whether the device communication task is a resource-constrained device communication task based on the task analysis results.

[0050] Specifically, step S142 is implemented as follows: The system acquires the basic attribute standards and communication performance standards for resource-constrained devices. It then compares the basic attribute information with the basic attribute standards to obtain a first comparison result, which includes hardware specification comparison results, energy information comparison results, and communication method comparison results. Finally, it compares the communication performance information with the communication performance standards to obtain a second comparison result, which includes processing energy efficiency comparison results, bandwidth utilization comparison results, and processing latency comparison results.

[0051] Step S143: Determine whether the device communication task is a resource-constrained device communication based on the first comparison result and the second comparison result.

[0053] Step S20: If the device communication task is resource-constrained device communication, then obtain the restricted message transmission protocol, construct the protocol stack according to the restricted message transmission protocol, and obtain the restricted message transmission protocol stack architecture.

[0054] Specifically, if the device communication task is resource-constrained device communication, a restricted message transmission protocol is obtained, which is obtained by simplifying a restricted application protocol; then, a protocol stack is constructed using the restricted message transmission protocol to obtain a restricted message transmission protocol stack architecture, which is then used to process the message format of the communication messages.

[0055] like Figure 5 As shown, step S20 specifically includes: Step S21: Based on the first comparison result and the second comparison result, if the device communication task is determined to be resource-constrained device communication, then obtain the corresponding restricted message transmission protocol according to the device communication task.

[0056] Specifically, step S21 is implemented as follows: After determining that the device communication task is resource-constrained device communication based on the first comparison result and the second comparison result, it is necessary to obtain a restricted message transmission protocol for resource-constrained device communication. Specifically, a restricted application protocol is obtained based on the device communication task, and redundant fields are removed from the restricted application protocol to obtain a first optimized protocol; the first optimized protocol is simplified by encoding to obtain a second optimized protocol, and the second optimized protocol is integrated by function to obtain a restricted message transmission protocol.

[0057] Step S22: Construct the application layer according to the restricted message transmission protocol to obtain the application layer structure, and construct the transport layer according to the restricted message transmission protocol to obtain the transport layer structure.

[0058] Specifically, step S22 is implemented as follows: After obtaining the restricted message transmission protocol, the message format of the messages to be communicated needs to be processed to facilitate device communication via the restricted message transmission protocol. This invention processes the message format of the messages to be communicated through a restricted message transmission protocol stack architecture, as shown below. Figure 6 As shown; specifically, the application layer is constructed according to the restricted message transmission protocol to obtain the application layer structure. The construction process of the application layer structure is as follows: the data format is set according to the restricted message transmission protocol to obtain the target data format, and the data content is simplified according to the restricted message transmission protocol to obtain the data simplification specification; the security mechanism is integrated according to the restricted message transmission protocol to obtain the target security mechanism, and the application layer is constructed according to the target data format, the data simplification specification, and the target security mechanism to obtain the application layer structure. The core function of the application layer structure is to encapsulate the generated raw data into standardized CoMP messages, ensure the minimization of redundant information by structuring the data content, and use a simplified message header containing only necessary fields.

[0059] Subsequently, the transport layer is constructed according to the restricted message transmission protocol to obtain the transport layer structure. The construction process of the transport layer structure is as follows: A transport protocol selection rule is formulated according to the restricted message transmission protocol; if message reliability needs to be guaranteed (e.g., control commands, status updates), the TCP protocol (Transmission Control Protocol) is used; if low latency and low overhead are desired (e.g., sensor sampling value reporting), the UDP protocol (Transmission Control Protocol) is used; protocol optimization measures corresponding to the transport protocol selection rule are set, enabling connection multiplexing on the TCP protocol to avoid resource consumption caused by frequent connection establishment or disconnection; for the UDP protocol, a retransmission mechanism (e.g., acknowledgment retransmission based on a time window) is introduced to improve reliability; an encapsulation method is set according to the restricted message transmission protocol to obtain the data encapsulation method, and the transport layer is constructed according to the protocol selection rule, the protocol optimization measures, and the data encapsulation method to obtain the transport layer structure.

[0060] Step S23: Construct the network layer according to the restricted message transmission protocol to obtain the network layer structure, and construct the link layer according to the restricted message transmission protocol to obtain the data link layer structure.

[0061] Specifically, step S23 is implemented as follows: The network layer is constructed according to the Restricted Message Transmission Protocol (RSP) to obtain a network layer structure. The construction process involves: performing IP address adaptation according to the RSP to obtain an IP address adaptation result; performing low-power wireless network adaptation according to the RSP to obtain a network adaptation result; and constructing the network layer based on the IP address adaptation result and the network adaptation result to obtain the network layer structure. This network layer structure directly supports standard IPv6 addresses (128 bits), is suitable for devices with full IP capabilities, and provides good routing scalability and address management capabilities. It is also optimized for ultra-low-power wireless networks (e.g., IEEE 802.15.4) by compressing the IPv6 header from 40 bytes to 1-2 bytes. Furthermore, it can automatically identify the underlying network type to dynamically select either IPv6 or 6LoWPAN encapsulation.

[0062] The link layer is constructed according to the restricted message transmission protocol to obtain the data link layer structure. The construction process of the data link layer structure is as follows: multi-interface compatibility is performed according to the restricted message transmission protocol to obtain interface compatibility results, wherein the interface compatibility results include wireless network interface compatibility, wired network interface compatibility, and Bluetooth interface compatibility; energy-saving mechanism integration is performed according to the restricted message transmission protocol to obtain mechanism integration results; and the link layer is constructed according to the interface compatibility results and the mechanism integration results to obtain the data link layer structure. The data link layer structure can automatically match the corresponding MAC layer protocol (e.g., IEEE 802.11, IEEE 802.3, IEEE 802.15.4).

[0063] Step S24: Construct the protocol stack based on the application layer structure, the transport layer structure, the network layer structure, and the data link layer structure to obtain the restricted message transmission protocol stack architecture.

[0064] Specifically, step S24 is implemented as follows: After completing the construction of the application layer structure, the transport layer structure, the network layer structure, and the data link layer structure, a protocol stack is constructed based on the application layer structure, the transport layer structure, the network layer structure, and the data link layer structure to obtain a restricted message transmission protocol stack architecture.

[0065] Step S30: Obtain the communication message to be communicated from the first device in the device communication task, process the communication message according to the restricted message transmission protocol stack architecture to obtain the target communication message, and transmit the target communication message to the second device in the device communication task according to the restricted message transmission protocol.

[0066] Specifically, to obtain the first and second devices in the device communication task, it is necessary to obtain the communication message to be communicated by the first device. The communication message to be communicated is obtained by the first device through message detection using a target message detection frequency. Therefore, before performing message detection, the first device needs to send the target message detection frequency. Specifically, it obtains the user's message detection frequency, verifies the message detection frequency according to the resource-constrained device corresponding to the resource-constrained device communication, and obtains a verification result. If the verification result indicates that the message detection frequency is not abnormal, the target message detection frequency is obtained based on the verification result. If the verification result indicates that the message detection frequency is abnormal, the message detection frequency is adjusted according to the verification result to obtain a frequency adjustment result, and the frequency adjustment result is sent to the user to remind the user to confirm the frequency adjustment result. When it is detected that the user has confirmed the frequency adjustment result, the target message detection frequency is obtained based on the frequency adjustment result.

[0067] Subsequently, the message to be communicated obtained by the first device through message detection based on the target message detection frequency is acquired, the message to be communicated is formatted according to the restricted message transmission protocol stack architecture to obtain the target message to be communicated, and the target message to be communicated is transmitted to the second device according to the restricted message transmission protocol.

[0068] like Figure 7 As shown, step S30 specifically includes: Step S31: Obtain the first device and the second device in the device communication task, send the target message detection frequency to the first device, and receive the communication message to be communicated sent by the first device, wherein the communication message to be communicated is obtained by the first device through message detection according to the target message detection frequency.

[0069] Specifically, step S31 is implemented as follows: The system acquires the first and second devices in the device communication task, sends the target message detection frequency to the first device, and after the first device receives the target message detection frequency, the first device performs message detection according to the target message detection frequency to obtain the message to be communicated, and returns the message to be communicated.

[0070] Step S32: Obtain the format information of the message to be communicated, and perform fixed header processing on the format information according to the restricted message transmission protocol stack architecture to obtain a first format. The fixed header processing includes identifying the version protocol, defining transmission semantics, determining the request type, and indicating the valid format.

[0071] Specifically, step S32 is implemented as follows: Before transmitting the message to be communicated, its format needs to be processed. The specific processing procedure is as follows: Figure 8 As shown, the format information of the message to be communicated is obtained, and the format information is processed with a fixed header according to the restricted message transmission protocol stack architecture to obtain a first format. The fixed header processing includes identifying the version protocol, defining transmission semantics, determining the request type, and indicating the valid format. That is, all CoMP messages start with a fixed 2-byte header, and all fields are extracted from the 2 bytes through bit operations, resulting in extremely high parsing efficiency. The detailed structure of the CoMP message is as follows: (1) Version number: VER (2 bits), which identifies the CoMP protocol version, for example, 01 represents version 1; (2) Message type: T (2 bits), which defines the transmission semantics of the message. For example, 00 represents an acknowledgment message, indicating that the receiver is required to reply with an acknowledgment; 01 represents an unacknowledgment message, indicating that no acknowledgment is required; 10 represents an acknowledgment message, indicating that the acknowledgment message is being responded to; 11 represents a reset message, indicating that the received message cannot be processed. (3) Request or response code: Code (2 bits) indicates the type of request or response. It is extremely simplified. For example, 00 represents GET (get resource); 01 represents POST (create or update resource); 10 represents Bad Request (error request); 11 represents ServiceUnavailable (service unavailable). (4) Content format: CF (2 bits), directly indicates the format of the payload, without the need for complex options, such as 00 representing application format or XML format; 01 representing application format or JSON format; (5) Message Identifier: MessageID (8 bits), used for matching requests and responses, and for detecting duplicate messages.

[0072] Step S33: Obtain the simplified message to be communicated according to the first format, perform payload encapsulation processing on the simplified message to be communicated to obtain the target message to be communicated, and transmit the target message to be communicated to the second device according to the restricted message transmission protocol.

[0073] Specifically, step S33 is implemented as follows: After obtaining the first format, a simplified message to be communicated is obtained according to the first format. The simplified message to be communicated is then encapsulated with a payload to obtain the target message to be communicated. Specifically, the message ID and current timestamp of the simplified message to be communicated are obtained, and the message ID and the current timestamp are combined by binary shifting to obtain a network resource electronic tag. The simplified message to be communicated and the network resource electronic tag are then encapsulated with a payload to obtain the target message to be communicated. The purpose is to encapsulate the necessary metadata (e.g., resource path, custom parameters) in the payload (e.g., in a JSON object), rather than transmitting it through separate option fields as in CoAP.

[0074] Subsequently, the target message to be communicated is transmitted to the second device according to the restricted message transmission protocol. After the second device receives the target message to be communicated, it performs tag calculation on the current timestamp in the target message to be communicated by binary shifting to obtain the tag calculation result. If the tag calculation result matches the network resource electronic tag, the target message to be communicated is considered to be legitimate and timely; if the tag calculation result does not match the network resource electronic tag, the target message to be communicated is discarded. The purpose is to effectively prevent message replay and spoofing attacks without increasing header overhead, and the computational overhead is much lower than that of a complete DTLS handshake.

[0075] Furthermore, such as Figure 9 As shown, the process involves obtaining the communication message to be communicated from the first device in the device communication task, processing the communication message according to the restricted message transmission protocol stack architecture to obtain the target communication message, and transmitting the target communication message to the second device in the device communication task according to the restricted message transmission protocol. The process further includes: Step S41: Detect whether the second device returns a message communication result within a preset time. Step S42: If the second device fails to return a message communication result within the preset time, a corresponding abnormal warning reminder is generated and sent to the user.

[0076] Specifically, the system checks whether the second device returns a message communication result within a preset time period; if the second device does not return a message communication result within the preset time period, a corresponding abnormal warning reminder is generated and sent to the user.

[0077] Furthermore, since CoMP primarily targets resource-constrained devices, its payload is often relatively small. In this invention, a performance metric E=1 / RTT is defined to represent the number of communications per unit time in the test environment, directly reflecting communication efficiency. Currently, this invention has been verified through numerous experiments, and the corresponding test results fully demonstrate the performance advantages of CoMP. Test data shows that in various inter-device communication scenarios, the round-trip time (RTT) of CoMP is shorter than that of CoAP, indicating higher transmission efficiency. The performance of CoMP-TCP (a TCP-based restricted message transmission protocol) is on average 17% higher than that of CoAP-TCP (a TCP-based restricted application protocol); the performance of CoMP-UDP (a UDP-based restricted message transmission protocol) is on average 35% higher than that of CoAP-UDP (a UDP-based restricted application protocol). The corresponding experimental results and related analysis are shown in the figures below. Figures 10 to 19 As shown.

[0079] The technical effects that this invention can bring are as follows: (1) The header is extremely simple, greatly reducing the protocol overhead. The CoMP header compresses all key information into 2 bytes and defines them through bit fields, eliminating the need for any variable length parsing. This makes the protocol data unit size of CoMP significantly smaller than that of CoAP. Smaller data packets mean lower network bandwidth usage and energy consumption. (2) The parsing complexity is drastically reduced, improving the processing speed. CoMP's fixed-length header means that the parser does not need to deal with complex variable-length fields and incremental encoding options; parsing a CoMP message only requires simple bit operations (e.g., masking and shifting) to extract all header fields. (3) Lower communication latency is directly due to the reduction in the complexity of the transmission protocol and the optimization of the data packet size; (4) Lower memory and computing resource requirements: Due to the simple protocol stack, CoMP requires less memory to store message states and processing logic during runtime, enabling CoMP to run on microcontrollers with more limited resources and lower costs, thus broadening the applicable boundaries of IoT devices. (5) The inherent ability to resist denial-of-service attacks prevents attackers from generating a "one-to-many" traffic amplification effect through the CoMP protocol, thereby improving network layer security. (6) Innovation and trade-offs in security mechanisms: Although this mechanism does not provide encryption, it provides a basic security verification scheme with lower overhead for communication between resource-constrained devices. It is particularly suitable for scenarios where encryption requirements are not high but message authenticity is required.

[0080] Furthermore, such as Figure 20 As shown, based on the above-described device communication method based on the Restricted Message Transmission Protocol (RSTP), the present invention also provides a device communication system based on the RTP, wherein the device communication system based on the RTP includes: The data analysis module 50 is used to acquire the user's device communication tasks, analyze and process the device communication tasks, obtain task analysis results, and determine whether the device communication task is resource-constrained device communication based on the task analysis results.
