An Improved Energy-Efficient PEGASIS-Based Protocol in Wireless Sensor Networks
EEPB (Energy-Efficient PEGASIS-Based protocol) is a chain-based protocol which has certain deficiencies including the uncertainty of threshold adopted when building a chain, the inevitability of long link (LL) when valuing threshold inappropriately and the nonoptimal election of leader node. Aiming at these problems, an improved energy-efficient PEGASIS-based protocol (IEEPB) is proposed in this paper. IEEPB adopts new method to build chain, and uses weighting method when selecting the leader node, that is assigning each node a weight so as to represent its appropriate level of being a leader which considers residual energy of nodes and distance between a node and base station (BS) as key parameters. The simulation results show that IEEPB has a better performance than EEPB on balancing energy consumption and prolonging lifetime of Wireless Sensor Networks (WSN).
