针对地质灾害检测的视频传感器覆盖的一种新算法*

在实际地质灾害监测工程中，为了使视频传感器这一有向传感器最大化覆盖，提出了一种全新的资源掠夺算法。该算法将相邻的节点看成树干上的叶片，利用树叶为争夺阳光而具有的特点使节点覆盖具有最大覆盖面积、最小的覆盖重合区域。从区域覆盖角度对算法进行仿真分析，证明了算法的可行性并且相对于传统算法覆盖效果好且高效，在相关应用中将有很大的优势。

New algorithm based on resource map for directional sensor networks

In the geological monitor's project,this paper proposed a new resource exploitation algorithm to enable the video sensors cover maximum area.The algorithm used the characteristics of competition for sunlight among leaves in a branch and regarded the adjacent nodes as the leaves to make the nodes get largest coverage area and minimum overlap area at the same time.This article uses simulation to analysis the performance of the algorithm from the perspective of regional coverage and proves the feasibility of t...
