Research on Optimization Method of LEACH Routing Protocol

In view of the problem of cluster head selection in traditional LEACH protocol, this paper considers the residual energy of node, distance from base station, density of surrounding node and so on, and puts forward the method of selecting cluster head by secondary competition law. Then, a simple optimization of intra-cluster communication is made, and the improved I-Leach algorithm is obtained. Through MATLAB simulation it is verified that the improved algorithm can effectively improve the network life cycle.
