Simulation and Analysis of Clustering Routing Protocol Based on Improved LEACH

In view of the problem that the random selection of LEACH Routing Protocol cluster head in WSN network will lead to the short lifetime of nodes and network, an e-leach protocol based on energy improvement is proposed in this paper, which optimizes the cluster head selection stage by considering both energy and distance factors, and introduces the average value of node residual energy, and the distance between nodes and base station as weight parameters to the threshold in the probability. A new threshold judgment formula is constructed, and the cluster head node is selected according to it, so that the node which is close to the base station, has more residual energy and less energy change is more likely to become the cluster head. The simulation results show that e-leach protocol can prolong the lifetime of network and nodes, and has better performance.
