摘要
针对无线传感器网络中覆盖空洞的现象,提出一种基于虚拟力的解决办法。为减少节点由移动所带来的能量消耗,该方法最多选择3个节点,通过节点移动并扩大其感知半径来修复覆盖空洞。实验结果表明该方法能保证较好的网络覆盖率,延长网络的生存时间。
This paper, in response to the phenomena of coverage holes in wireless sensor networks, proposes a solution method based on virtual forces. To reduce the energy consumption caused by node the movement, the method selects at most three nodes, and expands the radius of the sensor through moving the nodes to repair coverage holes. Experimental results show that the method can ensure a better network coverage and a longer network lifetime.
