摘要
针对未知环境下移动传感器网络的部署问题,提出了一种基于虚拟力的精确部署算法(virtual force based precision self-deployment algorithm,VFPSA).引入"引力线"的概念,并在此基础上构建节点与引力线之间的斥力,通过它们实现了Sink节点到目标Target路径的自动快速生成.模拟实验表明,与同类方法相比,该算法具有的平均移动距离和最大移动距离均更短,收敛时间更快.
To implement precision deployment of mobile sensor network in an unknown environment, a virtual force based precision self-deployment algorithm （VFPSA） is proposed. By introducing the concept of ＂attracting force line＂ and constructing virtual attracting force between attracting force lines and repulsive force among nodes, the paths between sinks and targets are created automatically. Simulation results showed that the proposed algorithm, when compared to similar methods, provides a short average moving distance with a short maximum moving distance and limited convergence time.
