摘　　要：无线传感器网络因其网络自组织,组网灵活,价格低廉等优点得到广泛的应用。但是无线传感器网络能源有限的缺点很大的制约着该技术的发展,所以无线传感器网络的节能技术受到研究者们越来越多的关注和重视,很多节能策略和算法随之而出。但是很多节能算法在考虑减少能耗的时候没有考虑系统可靠性的问题,这就使得应用该技术可能会导致系统可靠性降低。为提出一种基于数据压缩技术的节能策略,在一般的数据压缩技术的基础上,利用新的节能机制,提出一种可以根据条件决定系统在正常工作状态和节能工作状态之间合理切换的节能策略。根据合理的设计,可以使得无线传感器网络监控系统利用数据压缩技术来实现生命周期的延长。最后通过公式推导和仿真实验证明该节能策略确实提高了系统的生命周期。Wireless sensor networks（WSN） are widely used because of their advantages of self-organization,flexible networking and low cost.However,the limited energy resources of wireless sensor networks have greatly restricted the development of this technology.Therefore,the energy saving technologies of wireless sensor networks have attracted more and more attention of researchers,and many energy saving strategies and algorithms have emerged.Many energy saving strategies can not reasonably determine the switching time of energy saving state,which makes the reliability of the system decline.This paper proposes an energy saving strategy based on data compression technology.On the basis of general data compression technology,with the use of new energy saving mechanism.It can switch reasonably between the normal workong state and the energy saving working condition according to different conditions.According to reasonable design,the wireless sensor network monitoring system can use the data compression technology to achiene the extension of the life cycle.It is proved by the formula deduction and simulation that the energy saving strategy can improve the system life cycle.
