Abstract

[0002] Mesh is a multi-node, centerless, self-organizing wireless multi-hop communication network. Any wireless device node in the network can act as a router to send and receive signals, and can dynamically maintain connections and communications with other single or multiple nodes in any way.
[0003] The current resource occupation of Mesh ad hoc networks is through time division. Network nodes will have their own fixed time resources within a time period and can send data within this time resource.

[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0045] Figure 1 This is a flow chart of a Mesh self-organizing network expansion method provided in the first embodiment of the present invention. This embodiment is applicable to the case of expanding the capacity of a Mesh self-organizing network. The method can be executed by a Mesh self-organizing network expansion device. The Mesh self-organizing network expansion device can be implemented in the form of hardware and / or software. The Mesh self-organizing network expansion device can be configured in an electronic device. Figure 1 As shown, the method includes:
[0046] Step 110: Add multiple listening nodes in the Mesh self-organizing network according to the expansion request corresponding to the Mesh self-organizing network.
[0047] In this embodiment, specifically, the expansion request may include the number of nodes to be added. After obtaining the expansion request corresponding to the Mesh ad hoc network, multiple listening nodes may be added to the Mesh ad hoc network according to the number of nodes specified in the expansion request. Before the Mesh ad hoc network is expanded, the Mesh ad hoc network already includes multiple network nodes.
[0048] The difference is that each network node is fixedly allocated time resources for sending data by the Mesh self-organizing network; however, after registering and joining the network, each listening node is not fixedly allocated time resources for sending data by the Mesh self-organizing network.
[0049] Specifically, the network node and the monitoring node may be server devices.
[0050] Step 120: Control each of the monitoring nodes to access the Mesh self-organizing network at a fixed time according to a preset period agreed upon in the Mesh self-organizing network.
[0051] In this embodiment, after adding multiple listening nodes in the Mesh ad hoc network, each of the listening nodes can be controlled to periodically access the Mesh ad hoc network (that is, connect to the Mesh ad hoc network) according to a preset period. When the listening node is not connected to the Mesh ad hoc network, the listening node is only used to receive multicast or broadcast services of the network and cannot send service data.
[0052] In a specific embodiment, since the monitoring node can access the network regularly according to a preset period, the user can query the monitoring node that is executing the service in the Mesh ad hoc network.
[0053] Step 130: Complete the data transmission service corresponding to the Mesh ad hoc network through each of the network nodes and the monitoring node.
[0054] In this embodiment, after the Mesh self-organizing network is expanded, by distinguishing the newly added nodes (i.e., listening nodes) from the original nodes in the network (i.e., network nodes), and not allocating fixed time resources for sending data to the listening nodes, the time resources allocated to each network node will not be greatly reduced while ensuring the large-scale expansion of the Mesh self-organizing network, thereby reducing the impact on the network node data transmission delay and throughput. Secondly, the percentage of additional resources consumed in the periodic access process of many listening nodes to the total resources depends on the number of listening nodes and the access cycle. To a certain extent, as long as the access cycle is long enough, it is possible to support a sufficient number of listening nodes without significantly affecting the network throughput and delay.
[0055] In a specific embodiment, assuming that 20 network nodes are freely networked in close proximity, within a time period t1 (assuming t1 is large enough), the length of time each network node sends data is t2, and the delay in sending data is t3.
[0056] If the expansion request is to expand the network scale to 2000 nodes, according to the existing expansion method, when 2000 network nodes are freely networked in close proximity, within the t1 time period, the length of time each network node can use to send data is reduced to t2 / 100, and the delay in sending data increases to 100*t3.
[0057] Through the capacity expansion method of this embodiment, when the scale is 2000 network nodes (including 20 network nodes and 1980 listening nodes) in close proximity and free networking, within the t1 time period, assuming that the cycle of the listening node accessing the network is large enough, the length of time for each network node to send data is slightly less than t2, and the delay in sending data is slightly greater than t3.
[0058] The technical solution provided by the embodiment of the present invention adds multiple listening nodes in the Mesh self-organizing network according to the expansion request corresponding to the Mesh self-organizing network, controls each of the listening nodes, and regularly accesses the Mesh self-organizing network according to the preset period agreed in the Mesh self-organizing network. Through each of the network nodes and the listening nodes, the technical means for completing the data transmission service corresponding to the Mesh self-organizing network can achieve large-scale expansion of the Mesh self-organizing network without significantly affecting the data delay and throughput of the network nodes, thereby ensuring the data transmission performance of the Mesh self-organizing network after expansion.
[0059] Based on the above embodiment, the Mesh ad hoc network expansion method further includes: responding to a node type modification request triggered by a user through a file system, and modifying the node type of a target node in the Mesh ad hoc network according to the node type modification request.
[0060] In a specific embodiment, the role distinction between the listening node and the network node is achieved by setting parameters in the file system by the user, and the user can modify the node type of the network node and the listening node at any time by modifying the setting parameters in the file system.
[0061] Figure 2 This is a flow chart of a Mesh self-organizing network expansion method provided in Embodiment 2 of the present invention. This embodiment is a further refinement of the above embodiment. This embodiment is applicable to the situation where network nodes and listening nodes in a Mesh self-organizing network perform multicast services, such as Figure 2 As shown, the method includes:
[0062] Step 210: Add multiple listening nodes in the Mesh ad hoc network according to the capacity expansion request corresponding to the Mesh ad hoc network.
[0063] Step 220: Control each of the monitoring nodes to access the Mesh self-organizing network at a fixed time according to a preset period agreed upon in the Mesh self-organizing network.
[0064] Step 230: Send a broadcast packet or a multicast packet to a listening node within a preset range through a network node in the Mesh ad hoc network.
[0065] Step 240: Receive the broadcast packet or multicast packet through the listening node, and the network connection state corresponding to the listening node may be a disconnected state.
[0066] In this embodiment, when a network node performs a multicast service, it can send a broadcast packet or a multicast packet to all nearby listening nodes. The corresponding listening nodes will receive the broadcast packet or the multicast packet when the network node sends data without having to specifically access the network.
[0067] For broadcast packets or multicast packets sent by network nodes to listening nodes, there is no need to establish a link with the listening nodes, thereby achieving network node data throughput and data transmission latency that are no less than the scenario of data transmission services between network nodes.
[0068] The technical solution provided by the embodiment of the present invention adds multiple listening nodes in the Mesh self-organizing network according to the expansion request corresponding to the Mesh self-organizing network, controls each of the listening nodes, regularly accesses the Mesh self-organizing network according to the preset period agreed in the Mesh self-organizing network, sends broadcast packets or multicast packets to the listening nodes within a preset range through the network nodes in the Mesh self-organizing network, and receives the broadcast packets or multicast packets through the listening nodes. This technical means can achieve large-scale expansion of the Mesh self-organizing network without significantly affecting the data delay and throughput of the network nodes, thereby ensuring the data transmission performance of the Mesh self-organizing network after expansion.
[0069] Figure 3 This is a flowchart of a Mesh self-organizing network expansion method provided in Embodiment 3 of the present invention. This embodiment is a further refinement of the above embodiment. This embodiment is applicable to the case where the target network node and the target listening node in the Mesh self-organizing network perform unicast services, such as Figure 3 As shown, the method includes:
[0070] Step 310: Add multiple listening nodes in the Mesh ad hoc network according to the expansion request corresponding to the Mesh ad hoc network.
[0071] Step 320: Control each of the monitoring nodes to access the Mesh self-organizing network at a fixed time according to a preset period agreed upon in the Mesh self-organizing network.
[0072] Step 330: broadcast the ARP data packet to each node in the Mesh ad hoc network through the target network node in the Mesh ad hoc network.
[0073] In this embodiment, specifically, the target network node may be a network node in a Mesh ad hoc network that needs to send unicast data to a certain listening node.
[0074] Step 340: After receiving the ARP data packet through the target listening node, the target listening node is controlled to access the Mesh ad hoc network, and the unicast service is completed through the target listening node and the target network node.
[0075] In this step, specifically, the target listening node is a listening node that performs unicast services with the target network node.
[0076] In this embodiment, for the unicast service between the target network node and the target listening node, it is necessary to wait for the target listening node to access the network. Since there is a delay in the target listening node accessing the network, and the delay is controllable, it can be ensured that after the target listening node accesses the network, the data throughput and data transmission delay of the network node are close to the performance gap of the data transmission service between network nodes.
[0077] Step 350: After detecting that the unicast service between the target network node and the target listening node in the Mesh ad hoc network is completed, the target listening node is controlled to be disconnected from the Mesh ad hoc network.
[0078] The technical solution provided by the embodiment of the present invention adds multiple listening nodes in the Mesh self-organizing network according to the expansion request corresponding to the Mesh self-organizing network, controls each of the listening nodes, regularly accesses the Mesh self-organizing network according to the preset period agreed in the Mesh self-organizing network, broadcasts the ARP data packet to each node in the Mesh self-organizing network through the target network node in the Mesh self-organizing network, controls the target listening node to access the Mesh self-organizing network after receiving the ARP data packet through the target listening node, and completes the unicast service with the target network node through the target listening node, and after detecting that the unicast service between the target network node and the target listening node in the Mesh self-organizing network is completed, controls the target listening node to disconnect from the Mesh self-organizing network by means of technical means, which can realize large-scale expansion of the Mesh self-organizing network without significantly affecting the data delay and throughput of the network nodes, thereby ensuring the data transmission performance of the Mesh self-organizing network after expansion.
[0079] Figure 4 This is a flowchart of a Mesh self-organizing network expansion method provided in Embodiment 4 of the present invention. This embodiment is a further refinement of the above embodiment. This embodiment is applicable to the case where the target listening node and the target network node in the Mesh self-organizing network perform unicast services, such as Figure 4 As shown, the method includes:
[0080] Step 410: Add multiple listening nodes in the Mesh ad hoc network according to the capacity expansion request corresponding to the Mesh ad hoc network.
[0081] Step 420: Control each of the monitoring nodes to access the Mesh self-organizing network at a fixed time according to a preset period agreed upon in the Mesh self-organizing network.
[0082] Step 430: Control the target listening node to access the Mesh ad hoc network, and broadcast the ARP data packet to each node in the Mesh ad hoc network.
[0083] In this step, specifically, the target listening node may be a listening node in the Mesh ad hoc network that needs to send unicast data to a certain network node.
[0084] Step 440: After receiving the ARP data packet through the target network node in the Mesh ad hoc network, the target network node and the target listening node are controlled to complete the unicast service.
[0085] In this step, the target network node is a network node that performs unicast services with the target listening node.
[0086] Step 450: After detecting that the unicast service between the target network node and the target listening node in the Mesh ad hoc network is completed, the target listening node is controlled to be disconnected from the Mesh ad hoc network.
[0087] The technical solution provided by the embodiment of the present invention adds multiple listening nodes in the Mesh self-organizing network according to the expansion request corresponding to the Mesh self-organizing network, controls each listening node to access the Mesh self-organizing network according to the preset period agreed in the Mesh self-organizing network, controls the target listening node to access the Mesh self-organizing network, and broadcasts the ARP data packet to each node in the Mesh self-organizing network. After the target network node in the Mesh self-organizing network receives the ARP data packet, the target network node and the target listening node are controlled to complete the unicast service. After detecting that the unicast service between the target network node and the target listening node in the Mesh self-organizing network is completed, the target listening node is controlled to disconnect from the Mesh self-organizing network. This technical solution can achieve large-scale expansion of the Mesh self-organizing network without significantly affecting the data delay and throughput of the network nodes, thereby ensuring the data transmission performance of the Mesh self-organizing network after expansion.
