摘要
针对移动传感器网络中,数据的大规模定向传输的实际特性,提出一种基于虚拟力的移动传感器网络节点精确部署算法(VFPDA)。通过引入"中继节点簇"的概念,在源节点到目的节点之间生成多条虚拟"引力线",这些引力线相互衔接从而构成一条虚拟的通路,然后吸引周围的移动节点向其靠拢,在"引力线"所产生的引力以及节点之间的斥力等作用力的共同作用下,构建一条从源节点到目的节点的通路。实验仿真验证了该算法的有效性。
With the characteristics of massive directional transportation of data in the mobile wireless sensor network, a Virtual Force Based Precision Deployment Algorithm（VFPDA）is proposed. By introducing the concept of“relayed node cluster”, various virtual“attracting force lines”among the sink nodes and targets are constructed. These attracting force lines connect and develop into a virtual path, and attract the nearby mobile nodes to move towards them. With the efforts of attracting force caused by attracting force line and repulsive force caused between nodes, a connected path from sink node to target node is established. Artificial experiments validate the efficacy of the algorithm.
