Research On Clustering Routing Algorithms In Wireless Sensor Networks

The wireless sensor network is composed of many sensor nodes distributed in the monitoring area,and its main function is to realize data collection and transmission in the monitoring area.In wireless sensor networks,nodes are limited by their own energy,which increases the energy consumption of the node during data transmission,which hinders the development and application of wireless sensor networks.Equalizing node energy consumption and extending the network lifetime are important considerations in designing efficient routing protocols for wireless sensor networks.Based on the analysis and summary of various cluster routing protocols,two improved cluster routing protocols are proposed.The main content and work of the paper are as follows:(1)Firstly,the related theories of wireless sensor networks are described,and the principles and characteristics of plane routing and cluster routing are introduced.(2)Secondly,this thesis proposes a hierarchical multi-hop multi-path clustering routing protocol based on the energy of the nodes based on the energy of the nodes.(Energy Aware Multi-hop Multi-path Hierarchical based on inner and outer circle layering Routing Protocol,EAHMP).This algorithm revises the cluster head selection threshold formula,sets the relay node selection threshold formula,sets the network node from the distance from the node to the base station into the cluster form of the inner and outer circle cluster,selects the node data transmission route,and completes the data transmission between nodes.Through experimental analysis and comparison,it is found that the cluster size is reasonable,the node energy is balanced,and the data transmission efficiency is improved.(3)Finally,for large-scale networks,this thesis effectively divides the nodes in the network into sub-layers of the same size and improves the existing clustering mechanism.A multi-hop and multi-path routing protocol based on node energy and density is proposed(Energy Aware and Density Multi-hop Multi-path Hierarchical based on layering Routing Protocol,EADRP).In each network sublayer of the algorithm,the cluster head threshold formula is modified,and the minimum number of cluster nodes is maintained through the cluster clustering algorithm,which ensures efficient data transmission between clusters.Design the threshold selection formula of the relay node,select the best data transmission path,and complete the data transmission between the nodes.Through experimental analysis and comparison,it is found that in the same area size environment,the algorithm balances node energy and prolongs the network life cycle.
