A Multiple-Hop Energy Efficient Clustered Algorithm for Heterogeneous WSN

摘要

Wireless Sensor Network (WSN) attract lots of researchers because of its potential wide applications and special challenges. Developing an energyefficient routing protocol has a significant impact on the overall lifetime and stability of the sensor network. In this paper, we propose a multiple-hop energy efficient cluster algorithm, called MHEECA, to obtain an optimal path between cluster head nods and the base station for data transmission. With the help of Energy-Distance and weighted election probabilities of each node, we select the optimal energy-balanced cluster head nod, and all the nodes organize themselves into a cluster. After receiving the information from the member nodes, each cluster head node aggregates the data and transfers it to the base station by adopting multiple-hop communication path based on Dijkstra's algorithm. Simulation results show MHEECA is more efficient to reduce and balance energy consumption and hence prolong the lifetime of WSN.
