Energy efficient clustering routing protocol for wireless sensor networks

Wireless sensor networks (WSNs) have attracted extensive attention due to their wide range of potential applications. Network energy conservation, energy consumption reduction and lifetime extension are problems which must be solved. In this paper, some concrete analyses on the typical clustering protocols have been made, and based on the comparative study, an energy efficient clustering routing protocol——BCCP based on node correlation for wireless sensor networks is proposed. With the use of node location correlation and residual energy, energy consumption balancing algorithm reduces clustering iteration times. Then uniform distribution of cluster head nodes is obtained and communication energy consumption between cluster head nodes and member nodes is reduced. Therefore, the algorithm reduces energy consumption of network. With the use of data similarity and cooperative correlation among nodes, energy consumption reduction algorithm reduces data traffic of internal-cluster and external-cluster communication. Therefore, the algorithm reduces energy consumption of network. The experimental results show that BCCP has a distinct advantage in balancing, number of live nodes and reducing energy consumption comparing to other current methods.
