Research On Partitioned Heterogeneous Clustering Protocol For Wireless Sensor Networks

In wireless sensor network,routing protocol in the network layer is used to determine the arrival destination path,as one of important members of the TCP / IP protocol,the realization of the path choice of pros and cons will influence the efficiency of the whole network.Therefore,routing protocol selection is very important.A good routing protocol can prolong the network lifetime and improve the stability and throughput of the network.This paper will make a deep analysis summary of the WSN and the original correlation clustering routing protocol,for these protocols are currently existing network energy consumption is not balanced,and cannot efficiently solve the problems of the node deployment and heterogeneous networks in the cluster head distribution is not uniform,this paper focuses on WSN sub cluster routing protocol region division,reasonable and efficient deployment of nodes and on the basis of the effect of using the multi hop transmission on the network.The main research contents of this paper are as follows:(1)A new partition and heterogeneous clustering protocol(PHC protocol)for wireless sensor networks is proposed,in view of the problem of energy constrained and unbalanced consumption of nodes energy in single hop routing protocol for wireless sensor networks.The core of the protocol is the three different energy levels' the nodes,according to the different energy levels were deployed in different regions,the higher energy level of advanced nodes and intermediate nodes deployed in the area on both sides of the far away from the sink location,using clustering technology by cluster head to transfer data to the sink and lower level of ordinary nodes deployed in rendezvous point near to transfer data directly to the sink.(2)A partition and heterogeneous based on multi hop cluster routing protocol(MHP protocol)is proposed,according to general multi hop routing protocol exists for the energy consumption imbalance problem,combined with the advantages of heterogeneous networks in high energy nodes and characteristics of multi hop routing protocol,based on the idea of "partition".This protocol will be two different energy of nodes be deployed in different regions,the high energy of nodes deployed in the nearby centre,nodes with low energy deployed in the region far away from the focal point,through election of cluster head in the senior nodes to transit ordinary nodes collect data,aftet treatment and then transmitted to the sink.In this paper,the simulation experiments of two new protocols under the MATLAB environment,in order to verify that the two protocols are reasonable and effective,network stable period and throughput is selected as the evaluation criteria.The simulation results show that the new protocols can better balance of nodes and the whole network energy consumption,prolong the stable period and improve stability and throughput of the network,enhance the performance of the whole network.
