| 摘要: |
| 传统的固定无线传感器网络在进行目标跟踪过程中面临着跟踪质量较低、网络能耗较高等问题.移动传感器网络提供了新的解决方法，即移动式目标跟踪.目前的研究大多将被跟踪目标的探测和定位混为一谈.故此，区分了以探测为主和以定位为主的两类方法，着重介绍以探测为主的移动式目标跟踪方法的研究现状.通过对比现有方法在跟踪质量和网络能耗等方面的优缺点，揭示了现有研究存在的问题，总结了移动式目标跟踪领域存在的研究热点和趋势. |

| Abstract: |
| Traditional stationary wireless sensor networks usually have problems, such as low tracking quality, high energy consumption and so on, during the process of target tracking. More and more mobile elements, i.e., mobile sensors, are used in wireless sensor networks and thus bring new solutions for target tracking. The existing research usually confuses detecting the target with locating the target. After distinguishing between the detection-centric and localization-centric methods, this paper reviews specifically the current research status of the detection-centric target tracking methods. By comparing the merits and demerits of the existing methods in aspects like tracking quality, energy consumption, etc., it reveals their problems. In the end, it summarizes some possible research hotspots and tendency of mobile solutions in many aspects. |
