Abstract

The present invention provides an integrated sensing node device and a working method thereof, which mainly solve the problem of serious loss of information transmission in a wireless ad hoc network multi-hop transmission scenario. The array antenna unit of the node device of the present invention acts as a transmitting end and a receiving end, and interacts with the information processing unit two-way data, completes the sending and receiving of data between nodes, and receives the antenna control signal from the antenna control unit; the information processing unit and the antenna control unit 1. Two-way data interaction through the data interface, updating auxiliary data packets from the integrated routing unit, and transmitting information to the upper layer through the data interface. The integrated units of the node device work together to obtain the best mode of the transmit beam of the current node through the control algorithm of the antenna control unit. The invention considers adjusting the directional emission beam mode of networking nodes from the perspective of physical devices, enhances the anti-interference ability and survivability of the nodes, improves the multi-hop transmission performance of the self-organizing network, and can be used in the wireless self-organizing network communication system.

technical field

[0001] The invention belongs to the technical field of wireless ad hoc network communication, and in particular relates to a basic node device and a working method in a wireless Mesh network, in particular to an integrated sensing node device and a working method thereof, which can be used to implement wireless ad hoc network communication systems Improvement of multi-hop transmission performance. Background technique

[0002] The wireless Mesh network is developed from the wireless Ad-hoc network. The entire network does not depend on a dedicated infrastructure. Each node is mobile and can dynamically maintain contact with other nodes. Mesh networks are usually composed of Mesh routers and Mesh clients. Each node freely accesses the channel in a multi-hop sharing manner, avoiding network congestion caused by frequent service requests in traditional LANs. At the same time, its distributed network structure and re-routing function ensure that nodes in the net...
