面向目标跟踪的传感器网络睡眠调度协议

Sleep scheduling protocol for target tracking in sensor networks

移动目标跟踪是无线传感器网络中的一项重要应用,将睡眠调度机制引入到目标跟踪算法中可以大大降低能耗。针对目标跟踪的实际需求,提出一种面向目标跟踪的传感器网络睡眠调度协议。根据目标跟踪不同阶段,分别设计了目标跟踪前和跟踪过程中传感器节点的睡眠调度机制;另外给出了目标丢失时,如何唤醒节点继续跟踪目标的调度策略。结果表明:该算法能够在保证跟踪质量的同时,降低跟踪能耗。

Mobile target tracking is an important application in wireless sensor networks （WSNs）, in which introducing sleep scheduling can greatly reduce the energy consumption. A sleep scheduling protocol for target tracking in sensor networks is proposed for the actual demand of the target tracking application. This algorithm respectively designs two sleep schedulings for different phases of target tracking. It also provides a scheduling strategy how to wake up the sensor node guarantee to continue tracking it, when the mobile target lost. The experimental result show that this algorithm can greatly reduce the energy consumption, as well as ensure the tracking quality.
