摘要
分析了库仑力等四种多参数调节虚拟力模型对基于虚拟力的无线传感器网络覆盖算法性能的影响.采用覆盖增长率、算法迭代次数、覆盖效率以及节点平均移动距离四个性能指标对虚拟力模型进行了评价.结果表明含有引力系数、斥力系数和距离阈值三个参数调节的虚拟力模型,在覆盖效率等性能方面表现良好.
The in?uence of four virtual force models with multiple adjustable parameters,such as Coulomb force model,on the performances of coverage algorithm for wireless sensor networks(WSN) based on virtual force are described.Four evaluation factors are chosen to evaluate these virtual force models,these are coverage increment rate,iterative counts of algorithm,coverage efficient and average movement distance of nodes.The results show that,virtual force model with the three parameters,gravitation,repulsion coefficient and distance threshold,has better performance in the coverage algorithm of WSN.
