Strategy of energy balance based on data transfer for wireless sensor networks

In the wireless sensor networks,unbalanced energy consumption has a strong impact on the network lifetime.Characteristics of data switching and the energy consumption in circular region network are analyzed firstly.And then how to choose the optimal transmitting power to maximize the network lifetime is elaborated.Finally,the strategy is proposed about energy balance based on data transfer.Numerical simulation results show that the strategy can reduce the entire network energy consumption effectively and extend the network life cycle.
