An energy efficient routing protocol based on cluster head forecasting and power controlling

Due to the constrained energy of nodes without supply in wireless sensor networks, how to reduce energy consumption of nodes becomes the important target of routing protocols. An energy efficient routing protocol based on cluster head forecasting and power controlling (CHFPC) was proposed. In CHFPC, cluster head is forecasted based on both energy and distance parameters, and power controlling is introduced in cluster routing and data transmission in order to reduce energy consumption of nodes. Finally, the performances of the CHFPC algorithm are simulated with OMNeT++ platform. The results indicate that the energy efficient performance of proposed scheme is better than LEACH, the lifetime and residual energy of wireless sensor networks are improved by 23% and 15%.
