Wireless network ad hoc network method

Abstract

The wireless network ad hoc network method relates to communication network technology, and the present invention includes the following steps: 1) determine one node as the central node of the network, and other nodes as slave nodes, and then the central node selects an interference-free frequency point to send a network construction broadcast , the broadcast content includes the identification of the central node; 2) the frequency points supported by the scan from the node that does not join the network, calculate the Weight value of each neighbor node scanned, select the node with the largest Weight value as the parent node, and establish a connection with it to join the network 3) After the slave node joins the network, broadcast its own routing information, so that the lower nodes can join the network in time, and then complete the front-end pre-networking of all nodes; 4) The server establishes a network model according to the parameter information of each node, and optimizes the network structure and Network energy consumption, obtain the optimal network structure, and then send the routing parameters of each node in the optimal network structure to each node; 5) Each node adjusts its own routing parameters according to the routing parameters sent by the server. On the premise of ensuring high reliability of data transmission and network stability, the invention improves the anti-damage capability and strong self-healing capability of the wireless sensor network.

Description

technical field [0001] The present invention relates to the technical field of communication networks. Background technique [0002] The terrain along the railway line in the difficult mountainous area has great fluctuations and changes, strong tectonic activities, complex and changeable stratum lithology and climate, and frequent mountain natural disasters such as large-scale avalanches, rockfalls from high-level dangerous rocks, debris flows, and avalanches. It has the characteristics of strong destructive power, long development period and obvious spatial characteristics. Therefore, long-term automatic monitoring of geological disasters along railways in difficult and dangerous mountainous areas is an important part of ensuring the safety of railway operation and improving the ability of disaster prevention and mitigation. At present, the on-site data collection of automatic monitoring of geological disasters is mainly divided into wired and wireless methods. Due to the d...
