Abstract

The invention provides a communication device and system as well as method of a wireless cloud sensor network. The system comprises a plurality of wireless devices, and further comprises a cloud server which is connected with the wireless devices of the wireless sensor network through the Ethernet. The cloud server is used to search for transmission paths for the wireless devices through a communication path storage list and strength list of received signals according to requests of the wireless devices of the wireless sensor network, and generate communication path commands of the wireless devices according to the searching result and feed back the communication path commands to the wireless devices. The wireless devices are used to send transmission path requests of the wireless devices to the cloud server through the Ethernet according to information transmission requests of the wireless sensor network, and transmit information according to the received communication path commands of the wireless devices. The invention improves the performance of the wireless sensor network greatly, is low in cost and high in efficiency, and has high transmitting capacity and reliability.

Description

technical field [0001] The present invention relates to a wireless sensor network and cloud computing technical field, in particular to a wireless cloud sensor network (CWSN, Cloud Wireless Sensor Network) communication system, device and method. Background technique [0002] The wireless sensor network (wireless sensor network) is a wireless network whose main purpose is to collect information. The wireless sensor network contains multiple wireless devices. information to the data center. [0003] Generally, in wireless sensor networks, wireless devices in wireless sensor networks are divided into three categories according to their functions: nodes, repeaters, base stations, and data centers. The main purpose of the node is to collect information, and send the collected information to the base station wirelessly. Sometimes nodes need to pass multiple hops to transmit information to the base station, so wireless devices need to function as repeaters in wireless sensor net...

AI Technical Summary

Problems solved by technology

In most wireless sensor network application systems, due to the requirements of wireless device volume, cost, efficiency, etc., the signal processing and storage functions of the hardware in the wireless device are limited, which limits the development of wireless sensor network communication methods, and cannot Provide complex and powerful communication protocol methods, so the existing wireless sensor network communication protocol methods are generally relatively simple, which limits the information transmission capability and reliability of wireless sensor networks

[0007] That is, the wireless devices (including base stations, repeaters, and nodes) in the existing wireless sensor network use relatively simple communication protocol methods. The performance of these communication protocol methods, including wireless transmission capabilities, computing capabilities, and storage capabilities, is relatively limited. The wireless sensor network communication protocol method is implemented on the hardware of the wireless device, so the information transmission capability and reliability of the existing wireless sensor network are limited, and because it needs to be developed differently for different devices, the development Difficult and inefficient

[0008] This problem is especially serious in a system with a large number of wireless devices in a wireless sensor network, because when there are a large number of wireless devices, problems such as signal interference and channel congestion will be relatively serious, and choosing a better communication path requires powerful computing and storage. Space, and the wireless sensor network communication method of the wireless device in the existing wireless sensor network often does not meet the requirements
