摘　　要：首先推导出确定部署时基于V剖分感知误差最小,定义各个节点分区的覆盖权值。然后基于感知节点覆盖权值和虚拟力思想提出了一种部署优化算法,在确保感知不确定性最小化的同时保证网络连通性。最后仿真比较了在不同节点密度以及不同事件优先级下算法的部署性能,结果表明,本文提出的部署算法相比于其他算法能够有效地实现对热点区域的优化部署,保证较小的感知误差。In this paper,first,it is deduced that the sensor uncertainty is minimum with Voronoi partition;a node coverage weight by priority function of event area is defined.Then a nodes deployment optimization algorithm is proposed based on node coverage weight and virtual force.It guarantees the connectivity of network while the sensing uncertainty is minimal.Finally,computer simulation is carried to compare the deployability of the proposed algorithm with other algorithms under different node densities and different event priorities.Simulation results show that the proposed deployment algorithm is quick and effective with smaller sensing uncertainty compared with other deployment algorithms.Also the proposed algorithm has strong robustness.
