覆盖控制是传感器网络的基本问题之一,基于全向感知模型的覆盖控制的研究已经积累了丰富的成果.近年来,得益于图像/视频、红外、超声波等传感器的引入,有向传感器网络覆盖控制问题得到广泛关注并发展成为研究热点.从有向感知模型及其特点入手,综述了该领域国内外的研究进展,着重分类讨论有向传感器网络覆盖控制的基本理论和算法.最后提出当前亟待解决的问题,并对其未来的发展趋势进行展望.

Coverage control is a fundamental problem for wireless sensor networks, which has been explored thoroughly in the networks based on an omni-directional sensing model. Recently, thanks to the introduction of image/video, infrared, ultrasound sensors, coverage control algorithms for directional sensor networks have drawn more attention and have become a focus. This paper starts from the concept and characteristics of directional sensing model, and then summarizes the current research progresses at home or abroad. The study also classifies and summarizes the basic coverage control theories and algorithms in the context of directional sensor networks. Finally, the paper points out the open research problems to be solved and the future trends.
