An Energy-Balanced Clustering Routing Protocol for Wireless Sensor Networks
Wireless Sensor Networks have many limited capacities such as battery power, computation and communication bandwidth, how to balance the energy dissipation and prolong the network lifetime is a key problem. Based on the extensive analysis of LEACH algorithm, EBCP algorithm is proposed. It considers the nodes’ energy when clustering, and takes the nodes’ energy as a factor of the cluster head election: Increasing the probability to be cluster head of the higher-level energy nodes, and decreasing the probability to be cluster head of the lower-level energy nodes, so the nodes can adjust their probability to be cluster head as to their energy. Simulation results show that the modified algorithm can balance the energy distribution of the network and achieve better performance than LEACH in terms of the network lifetime.
