中文摘要：

针对单一中心的节点非均匀有向传感器网络部署的局限，提出了多中心的节点部署算法PFMCA（potential field based multi—center algorithm）。在部署中心概念及移动策略的基础上，能够保证多个监测中心的覆盖质量，同时实现对其余区域的均衡且尽可能高效的覆盖。仿真实验的结果分析表明，算法实现了对多个重点监测区域的高覆盖质量，且在多中心点间的区域具有更好的覆盖均衡性。

英文摘要：

For the single point of non-uniform directional sensor network deployment restriction, this paper proposed algorithm based on the sensor deployments of multi-center. In the deployment center concept and strategy on mobile, it ensured the case of the coverage quality of multiple monitoring priorities, and achieved as efficiently as possible and balanced coverage of the remaining area. The simulation experiment＇ s results show that this algorithm achieves high coverage quality for multiple key monitoring regional blocks, and more excellent equilibrium in the coverage area across multiple centers.
