针对节点随机分布的无线传感器网络,提出一种基于模糊决策的导标引力移动模型.利用收集到的节点信息,根据构建的虚拟引力规则,调整移动方向及移动速率.仿真结果表明,该路径规划方法适应网络拓扑,可缩短导标遍历过程中的路径长度,提高路径的有效率,节省能量开销.

For wireless sensor networks （WSN） with nodes ran- dom distribution, a gravitation model for beacon＂ movement based on fuzzy decision was proposed. The beacon adjusted its motion direction and speed according to the nodes＇ information gathered and the rules of the virtual force. Simulation results show that the proposed method can adapt the network topology, which shortens the path length of beacon traversing the whole network, while enhancing the path＇s validity and saving the en- ergy consumption.
