摘要
覆盖和连通是无线传感器网络中两个密切相关的基本问题,直接影响着网络性能和网络任务完成的质量。文章给出了传感器节点的感知模型,从不同角度对覆盖问题进行了分类,阐述了覆盖控制算法的评价指标,介绍了覆盖问题和连通问题的典型算法,最后对覆盖和连通问题的研究方向进行了展望。
Coverage and connectivity are two closely related fundamental issues in wireless sensor networks, which causse a direct impact on network performance and the quality of the network task. The paper gives the perception model of sensor nodes, classifies the coverage issues from different angles, sets forth the evaluation indexes of coverage control algorithm and introduces the typical algorithm on coverage issues and connectivity problems. Finally, it also gives prospects of the coverage and connectivity question in wireless sensor networks for future research directions.
