移动异构传感器网络分布式部署算法

摘要

针对移动异构传感器网络中的最大覆盖问题,论文提出了一种分布式部署算法.该算法依据节点坐标及其感知范围而更新目标划分子区间,使子区间内的各个节点能结合自身及其delaunay邻居节点当前的几何位置和剩余能量值确定速度向量,同时利用节点的移动特性,使调整后的网络最大化覆盖目标区域.仿真结果表明,该算法在提高网络覆盖率和协调速度的同时,能兼顾网络节点剩余能量的均衡.%According to the maximum coverage problem of heterogeneous mobile sensor networks,a distributed de-ployment algorithm is proposed. By updating the target division subintervals based on the coordinates and sensing ranges of different nodes,the algorithm makes the node in every subinterval determine its velocity vector,which is related with the current location and remaining energy of the node and its delaunay neighbor nodes. Taking advan-tage of the mobility,the nodes would most likely to cover the target area. The simulation results show that this algo-rithm can improve the coverage rate and coordination speed of the network,as well as enhancing the balance of the residual energy of different nodes.
