Research On Partition Based Wireless Sensor Network Routing Protocol

A wireless sensor network is a communication network that collects data information in its detection area.It can quickly collect relevant data within its own monitoring range and transmit it to the corresponding base station for processing.Because the data collected by the wireless sensor network has extremely high time correlation and spatial correlation,if the sensor uses the compressed sensing theory when collecting information,it will help the system to reduce the amount of data transmission,thereby saving energy consumption,thereby making the energy of the entire network.The utilization rate is improved and the network life is prolonged.Therefore,the application of the compressed sensing theory to the data acquisition process of wireless sensor networks has important theoretical and practical value.This paper firstly summarizes the research status,network characteristics and routing protocols of wireless sensor networks at home and abroad,and analyzes the characteristics of classical planar routing protocols and hierarchical routing protocols.Then,the nodes of wireless sensor networks are caused by the uneven energy consumption.A short life span problem is proposed.A new wireless sensor network partition routing protocol is proposed,and the node transmission path in the region is optimized by the elite ant colony algorithm.The main work is as follows:(1)The Compressed Sensing(CS)theory is introduced into the data collection and processing process of the wireless sensor network node,and a large amount of redundant information collected in the information data is eliminated,so as to save the network energy consumption in the data transmission process.Then,the monitoring area is partitioned by the angle of the node and the aggregation node,and each partition and the node after the partition are confirmed,and then the sensor node in each partition generates a path with the sink node as the end point,and the transmission sensor node collects the collected data.data.(2)Using the elite ant colony algorithm in each area after the partition,find the shortest path that saves network energy consumption in each area,and thesensor node transmits the collected data through the path found by the elite ant colony algorithm.The data is finally processed at the aggregation node.(3)After the node zoning in the monitoring area is partitioned according to the above zoning method,some nodes at the boundary of each area are controversial,and some nodes may not belong to a path area that can save energy.For disputed boundary nodes,they are secondarily partitioned according to their distance from other neighbor nodes.Compared with the previous partitioning method,this method saves network energy consumption and extends the network life cycle.
