摘要
水下无线传感器网络作为三维立体监视体系的重要组成部分,其覆盖模型、拓扑控制和能量消耗一直是三大重要基础性研究领域。基于水下监视网络节点随机部署策略研究传感器网络三维覆盖问题,针对水下固定锚节点部署后水平位置不能改变的问题,提出基于加权二分图最大匹配的节点沉降算法,保证所有匹配节点沉降后与理想图案位置的水平距离偏差总和最小,针对三维空间覆盖空洞问题,提出一种基于三维泰森晶胞体结构的覆盖空洞修复算法。仿真结果表明,提出的算法与国外同类算法相比,网络覆盖率提高达7%以上。
Underwater wireless sensor network is an important component of 3 D tactical surveillance system,and its coverage model,topology control and energy consumption are the three most important basic research topics. Researching the problem of sensor network 3 D-coverage based on the random deployment strategy of underwater monitoring network nodes,focusing the problem that nodes will be fixed by the anchors on the seabed,a node sinking algorithm is proposed based on a weighted complete bipartite graph. Then a coverage hole repairing algorithm is proposed via 3 D-Voronoi polyhedron and K-means clustering to improve the coverage ratio. Simulation result shows that compared with the peer algorithms,the proposed algorithm has good performance in network coverage and comparable network connectivity.
