摘要
为了解决稀疏网络环境下传统虚拟力算法在部署节点过程中出现的网络分割、覆盖漏洞以及无法对检测区域进行重点监测的问题,提出了抗分割的移动传感器网络自部署算法.通过构建节点间的虚拟斥力、节点的运动方程以及监测空间中的虚拟引力场,使网络具备了重点覆盖、自修复、抗分割能力.模拟实验表明,该部署方法进一步增强了移动传感器网络的覆盖性能.
An anti-partition self-deployment algorithm （APSDA） is proposed to solve the problems of network-partition, coverage-holes and lacking of key-sensing which disturb conventional virtual force algorithm （VFA） deployment approach in sparse network environment. By constructing the virtual repulsive force between nodes, the movement equation and the virtual attracting-field in the sensing area, the capability of self-repair, key-coverage and anti-partition are achieved. Simulation shows that the performance of network is enhanced by APSDA.
