Problems solved by technology

In WSN, the death of a node in a certain area will inevitably lead to incomplete data monitoring in this area, which in turn will lead to unreliable network performance in this area
In the traditional WSN routing algorithm, all nodes aim to monitor the entire area. As time goes by, nodes will die randomly in the entire area, which leads to the inaccurate data monitoring of all areas in the later stage of the wireless sensor network. reliability

Embodiment Construction

[0024] In order to facilitate management, the monitoring area is divided, and monitoring base stations are established near the monitoring area as the central information control system.

[0025] Deploy corresponding sensor nodes in the area, the base station sends a message to the node to wake up the node, the node sends positioning information and energy information to the base station, the base station judges the node with the best signal-to-noise ratio in each area according to the received information status, and sets it It is the cluster head node, and the authority is delegated to make the cluster realize autonomy.

[0026] The cluster head node sends a message to the members in the area, and the cluster members reply the message and apply for establishing routing information, and the cluster head node establishes a routing table and collects the remaining energy of each node. The cluster head node calculates the energy threshold according to the energy information and ...

Abstract

The invention relates to a wireless-sensing-network autonomous routing method. The wireless-sensing-network autonomous routing method comprises the following steps of step1, constructing a network topology for a wireless sensor network; step2, in the wireless sensor network, dividing a monitoring area, selecting a cluster head node in each area according to an optimum signal to noise ratio strategy and establishing a cluster group in the area after the cluster head node is selected; and step3, establishing a routing table between the cluster head node and a member, collecting residual energy information of cluster members, calculating an energy threshold according to the information and carrying out cluster head rotation according to the threshold. The method has advantages that node energy consumption is reduced and a network life cycle is prolonged; network congestion is reduced so as to guarantee network fairness; and information transmission reliability is increased.

Description

technical field [0001] The invention relates to the technical fields of wireless sensor network, routing protocol, channel state and wireless communication, in particular to a wireless sensor network autonomous routing selection method. Background technique [0002] Wireless communication network technology has advanced by leaps and bounds and developed rapidly in the past few decades. As a special branch of the field of wireless ad hoc networks, wireless sensor networks have similar characteristics to wireless ad hoc networks and unique characteristics different from other wireless networks: the performance of sensor nodes is limited. Due to factors such as cost and size, the functions, battery capacity, computing and storage capabilities, and communication capabilities of wireless sensor nodes are all limited. Wireless sensor nodes have limited working time, low processing power, small memory capacity, and short communication distance. Dynamic topology, wireless sensor n...
