针对三维传感器网络中节点最优部署问题进行研究.通过分析常用规则多面体(如立方体和截顶八面体等)在三维空间的填充特点,提出了网络节点按规则多面体部署时,单位节点最大有效体积的计算方法;同时利用该方法得到了网络区域保持充分覆盖且邻节点相连接时所需的最少节点数;最后通过仿真比较了不同规则多面体的部署性能,进而给出了在各种rc/rs(rc为通信范围,rs为感测范围)情况下的最优部署模式,提高了网络节点的部署效率.
The optimal deployment of nodes in three-dimensional sensor networks is studied.Through the analysis of the filling characteristics of common rules polyhedron (such as cube and truncated octahedron, etc.) in the three-dimensional space, the maximum effective volume per unit node At the same time, we use this method to get the minimum number of nodes needed when the network area is fully covered and the neighboring nodes are connected. Finally, we compare the deployment performance of different regular polyhedron by simulation, (rc is the communication range, rs is the sensing range), the optimal deployment mode improves the deployment efficiency of network nodes.
