Abstract: In order to avoid network segmentation in Mobile Wireless Sensor Network(MWSN),a distributed node path selection algorithm based on right hand rule is proposed.The Sink node is mainly used to initialize the network in MWSN.It uses right hand rule to calculate the position and orientation of mobile sensor node to maintain the network connectivity.Each sensor node can send the sensed data back to the Sink node to improve the coverage of MWSN.Experimental results show that the algorithm can avoid network segmentation and improve the survival time and overall efficiency of MWSN.

Key words: Wireless Sensor Network(WSN), Mobile Wireless Sensor Network(MWSN), network segmentation, path selection;right hand rule

摘要: 针对移动无线传感器网络(MWSN)中的网络分割问题,提出一种基于右手法则的分布式节点路径选择算法。在MWSN中,以Sink节点为主对网络进行初始化,利用右手法则计算移动传感器节点所需移动的位置与方向,以维持整个网络的连通性,并使每个传感器节点都能将感测数据回传至Sink节点,提高MWSN的覆盖范围。实验结果表明,该算法能避免网络分割的产生,提高MWSN网络生存时间及整体效能。
