| 摘 要： | 无线传感器网络由于其自组织性、鲁棒性及节点数量巨大的特点，非常适合于目标跟踪。无线传感器网络目标跟踪大体分为单目标跟踪与面目标跟踪。单目标跟踪主要采用双元检测协作跟踪、信息驱动协作跟踪、传送树跟踪算法等方法。面目标跟踪采用对偶空间转换算法等方法。在无线传感器网络目标跟踪中，跟踪精度、跟踪能量消耗和跟踪可靠性是需要考虑的主要问题。

| Abstract: | The Wireless Sensor Network (WSN), because of its self-organizing characteristic, robustness and huge quantity of nodes, is perfectly suitable for target tracking. Now, there are two main aspects of target tracking in the WSN-single-target tracking and multi-target tracking. Cooperative tracking with binary-detection, information-driven dynamic collaboration, and dynamic convey tree-based collaboration are designed for single-target tracking. Dual-space approach is for multi-target tracking. Tracking precision, reliability and energy consumption are the most important issues in the WSN tracking requiring thorough consideration. |
