中文摘要：
移动目标跟踪是传感器网络的一个重要应用．网络中传感器节点协作发现目标并将对目标的感知信息反馈给用户．为了有效地减少网络能耗和提高跟踪质茸，文中提出一种基于两阶段睡眠调度的目标跟踪协议．该协议将整个跟踪过程划分成两个阶段，根据各阶段对节点密度要求的不同，分别采用不同的睡眠调度机制．文中进一步对所提出协议进行优化，在保证跟踪质量的同时最小化系统能耗．最后用36个传感器结点验证了所提出协议的有效性．
英文摘要：
Mobile target tracking is an important application in wireless sensor networks, in which all sensor nodes collaborate to discover the target and report its location information to us- ers. To conserve energy in networks and improve tracking performance, the authors propose a two-phase sleep scheduling based tracking protocol. It divided the whole tracking procedure into two phases and schedule nodes differently at each phase. The authors further optimized the node scheduling protocol to minimize the energy consumption with guarantee of tracking quality, and evaluate the method in an indoor environment with 36 sensor nodes. The experimental results show that the protocol performs better in terms of tracking quality and energy consumption.
