The wireless sensor networks have been extensively deployed and researched. One of the major issues in wireless sensor networks is the energy consumption program. In this paper, we analyzed the development status of wireless sensor networks and the problems,while proposed the network structure and energy model,then we discussed the energy saving strategies for wireless sensor networks from four aspects:First analysis the component of WSN protocol stack and the energy consumption;Second,we study the energy-saving strategy for a single node from the computing subsystem and the communication subsystem,and we introduce a new long-sleeping status to save energy through using Flag mark.Third is the energy-saving optimization strategy based on communication protocol which mainly discuss from MAC and routing protocols.Last,we discuss the topology control strategy for energy-saving and point out the importance of topology control technology. Use these strategies, we can significantly reduce the energy consumption of wireless sensor networks and extend the network life-cycle.

Topology control is an efficient approach which can reduce energy consumption for wireless sensor networks, and the current algorithms mostly focus on reducing the nodes’ energy consumption by power adjusting, but pay little attention to balance energy consumption of the whole network, which results in premature death of many nodes. Thus, a distributed topology control algorithm based on path-loss and residual energy (PRTC) is designed in this paper. This algorithm not only maintains the least loss links between nodes but also balances the energy consumption of the network. The simulation results show that the topology constructed by PRTC can preserve network connectivity as well as extend the lifetime of the network and provide good performance of energy consumption.
