摘要： 针对现有无线传感器网络区域覆盖控制算法很难在确保网络连通率的同时对网络覆盖率和能耗进行优化的问题,本文提出一种基于连通支配集的区域覆盖控制(area coverage control based on connected dominating set,ACCBCDS)算法。当节点随机分布于监测区域后,未连通的节点移向Sink节点直至网络实现全连通,之后利用三着色算法构建网络连通支配集,Sink节点对非连通支配节点进行集中式优化调整,让非连通支配节点移至更优位置。在优化调整的过程中同时考虑了网络连通率、覆盖率和节点移动距离。仿真结果表明,与典型的基于虚拟力的区域覆盖控制(area coverage control based on virtual forces,ACCBVF)算法相比较,本文提出的ACCBCDS算法能使网络在确保全连通的前提下获得更高覆盖率,并能减少网络覆盖控制中的移动能耗。

Abstract: To solve the problem that existing area coverage control algorithms for the mobile WSNs are difficult to ensure the network connectivity rate of the network coverage and energy consumption optimization, an area coverage control algorithm based on connected dominating set (ACCBCDS) algorithm is proposed for the mobile WSNs. When the nodes are randomly distributed in the monitoring area, nodes disconnected to the Sink node are required to move toward the Sink node until full network connectivity is achieved. Then the three-staining method is adopted to construct the network connected dominating set, after which the Sink node performs centralized optimization adjustment on dominated nodes, requiring dominated nodes to move toward better locations. During the adjustment, network coverage rate, connectivity rate and node movement distance are synthetically considered. Simulation results show that compared with typical area coverage control algorithm based on virtual forces (ACCBVF) algorithm, the proposed ACCBCDS can achieve higher network coverage rate under the premise of ensuring full network connectivity, and decrease node movement energy consumption during network coverage control.

Key words: sensors networks, connected dominating set, coverage rate, energy consumption
