Analysis And Research Of WSNs Routing Protocol Based On Improved LEACH

Wireless sensor networks(Wireless sensor networks,WSNs)have the characteristics of selforganization,random distribution and wide application.They play an irreplaceable role in the fields of environmental monitoring,target positioning,health monitoring,crisis management,national defense.Faced with different applications,different routing protocols need to be designed,due to the particularity of the WSNs deployment environment.With limited energy,how to ensure the accuracy of data transmission,improve the energy utilization of each node in the network,and extend the life cycle of wireless sensor network has become the focus of attention.In this context,this paper focuses on the WSNs-level routing protocol,through the improvement of the standard whale optimization algorithm and the minimum spanning tree strategy,the LEACH protocol is optimized and improved to improve the energy utilization of the internal nodes of WSNs and prolong the life of the network.The specific research contents are as follows:(1)Aiming at the problem of improper cluster head selection in the LEACH algorithm,resulting in short network life and low node energy utilization,a whale optimization algorithm is introduced to improve the clustering mechanism.A WSNs clustering algorithm based on whale optimization algorithm(CSWOA-LEACH)to optimize the cluster head structure.(2)Aiming at the optimization of LEACH algorithm cluster head transmission path selection,the minimum spanning tree algorithm is introduced to construct the optimal transmission path,and an improved algorithm CSWOA-NST-C based on whale optimization algorithm and minimum spanning tree is formed.On the one hand,it improves the efficiency of information transmission,reduces the energy consumption of nodes and prolongs the network life.On the other hand,it increases the number of packets received from the base station,thus improving the ability to obtain network information.Finally,through comparative analysis of simulation experiments,we can see that the CSWOA-NSTC algorithm has made great progress over the LEACH protocol in terms of network life cycle,total energy consumption of network nodes,and number of packets received by the base station.
