Collaboration Model Based on Equilibrium Strategy for Wireless Sensor Networks

Base on collaboration model of optimal search theory in discrete spaces, an energy balancing collaboration model and its solution algorithm in wireless sensor networks are proposed in this paper by taking all the following factors into consideration: the costs and benefits of node to forward data, energy consumption, and the behavior of adjacent nodes in the past. The objective of the algorithm to balance the energy consumption and maximize the network lifetime. An energy factor and number of packets transmitted are presented to make the energy consumption of the network tend to equilibrium and maximize the network lifetime. A numerical example illustrates the validation of the proposed collaboration model and policy.
