Abstract
To extend the survival time of the Wireless Sensor Networks (WSNs) and decrease the energy it consumes. The method of multiple attribute decision making is used in Leach: firstly, the distance between the node and the base station, the surplus energy of nodes and the amount of neighbor nodes of each node are optimization properties which can obtained the set of optimal Cluster Heads(CHs) in each round; Then using the minimum Manhattan distance method to select and sort the sensor nodes in the set then the optimal nodes are chosen as the CHs. According to a large number of simulation experiments, the proposed protocol is more reasonable for the selection of CHs in the network, the distribution of death nodes is outside-in and the energy load is more balanced.
