摘要: 针对无线传感器网络中单纯路由控制或拓扑控制节能效用有限的问题,提出虚拟节点概念,并使用最小覆盖近似算法,给出虚拟节点在检测区域中的分布及基于虚拟节点的拓扑控制描述,在此基础上提出一种基于拓扑控制技术的组网近似算法。实验结果表明,该算法在节点数为1 500、覆盖半径分别为80、85、110时,完成传输数是单纯采用EOLSR算法的15.7倍、12.0倍和18.1倍,明显提高了节能效用。

Abstract: Aiming at the problem of the energy-inefficiency of taking routing control or topology control only in Wireless Sensor Network(WSN). This paper considers a combination and presents a new concept: virtual node, gives the distribution of virtual wireless sensors in the detection area and a description of topology control based on virtual wireless sensor technology using the minimum cover approximation algorithm, and proposes a networking technology based on the above control technology. Experimental results show that, when node number is 1 500 and covering radius is 80, 85 and 110, the transmission number under the method is 15.7, 12.0, 18.1 times better than that under EOLSR, and the algorithm can significantly improve the energy-saving utility.

Key words: approximation minimal covering algorithm, Wireless Sensor Network(WSN), topology control, energy-efficient networking, EOLSR routing algorithm, combination technique
