摘要
从覆盖面积和有效覆盖率2个方面评估了正三角形网格和正四边形网格的性能优劣.根据理论分析和公式推导,将三维区域完全覆盖问题转化为多个平面覆盖问题研究.采用性能较好的正三角形网格进行节点部署,从拓扑学的角度给出了一种三维区域完全覆盖的部署策略,提供了所需的最少节点数的数学表达式,进行了仿真验证.
The performance of regular triangle grid and square grid are evaluated from two aspects： coverage area and effectual coverage rate.The 3-dimensional coverage problem is transferred to several planar coverage problems to solve.The regular triangle grid which has better performance is adopted to deploy nodes and a full coverage deployment strategy in 3-dimensional is proposed from the viewpoints of topology.The strategy gives the expression of minimum number of nodes for deployment and has been proved by simulation.It has guidance meanings for practical application.
