摘　　要：鉴于移动无线传感器网络的节点在群组移动过程中会破坏网络整体连通性的情况,基于节点本身的移动特性,分别提出了构建连通路径以及记号路径的解决方案。通过优化路径节点数,均衡路径节点的能耗以及判定各节点的移动指数,最终依靠节点的级联移动或者有序脱离完成相应链路的构建。仿真分析表明,方案能够有效地保证群组移动后网络的连通性。Group mobility of sensor nodes in the mobile wireless sensor networks（MWSNs）may cause great damage to the overall connectivity. A scheme for constructing communication path and mark path, which is based on the mobile characteristics of the nodes themselves, has been proposed to solve the problem. This method is able to complete the construction of the corresponding links through the cascaded movement and ordered break oI sensor nodes, cing the energy consumption and judging the mobile index of each node. connectivity of networks effectively. by optimizing the number of nodes in the path, balan Experimental results show that the scheme can keep the
