摘    要:针对事件监测应用的特点,提出了一种简单、有效的基于栅格的无线传感网感知调度方法.该方法首先对目标环境进行栅格划分,然后由栅格内的节点选举出代表轮流执行监测任务,具有通信开销小、电量消耗均衡,可扩展性好的特点.通过分析和模拟可知,基于栅格的感知调度可以获得与节点密度成正比的电量节省,并且在事件监测质量上优于随机调度方法.而且,通过调整栅格尺寸和节点工作时间,可以为平衡网络寿命和发现延迟提供有效的手段.

关 键 词:无线传感网  事件监测  节能  感知调度  发现延迟

Abstract:In this paper,an efficient grid-based sense scheduling method for event detection in Wireless Sensor Networks is proposed.After grid-partitioning sensors in target environment,the sensors within each grid elect one representative to carry up the sense task in turn,which has low communication overhead,balanced energy consumption and good scalability.It is shown by analysis and simulation that the grid-based sense scheduling can achieve energy saving proportional to the node density and better detection delay than random scheduling.The method also provides means to balance network lifetime and detection quality by adjusting size of grids and duty time of nodes.
Keywords:wireless sensor networks  event detection  energy saving  sense scheduling  detection delay
