| 摘 要： | 节点覆盖是无线传感器网络关键技术之一。该文提出一种基于虚拟力的异构节点网络覆盖增强算法，该算法由计算几何和改进的虚拟力算法组成。研究如何在理想状态下使分布达到覆盖度最大化，同时采用虚拟势场方法使节点作扩散运动，以消除网络感知重叠区。仿真实验结果表明，网络覆盖度提高约20％。

| Abstract: | Node coverage is one of the key techniques in Wireless Sensor Netwok(WSN).This paper presents a coverage-enhancing algorithm for non-isomorphic node network based on virtual force,which consists of computational geometry and improved virtual force algorithm.How to maximize the coverage in ideal state is studied.By using virtual potential field,nodes repel each other,which eliminates the sensing overlapping regions.Simulation experimental results show the coverage rate increases by about 20%effectively. |

| Keywords: | Wireless Sensor Network(WSN) non-isomorphic virtual force coverage rate |
