摘　　要：超宽带定位技术应用于移动传感器网络路由算法是目前研究热点,该文提出一种基于超宽带定位的源动态路由算法,通过超宽带定位建立网络拓扑,并根据节点移动速度来反映节点的移动效应;通过受限泛洪和移动预测两种路由机制来提高路由性能。仿真结果表明,该算法能提高移动节点的路由成功率,降低路由平均延时。Applying UWB positioning technology to the routing algorithm in the WSN has become the hot spot of research.The paper proposed a routing algorithm based on UWB positioning dynamic source routing.The network topology was established through the UWB positioning and the node speed was used to reflect the mobility effect of the node.Two routing schemes,that is,the restricted range of flooding and the mobility,were used to enhance the routing performance.The simulation demonstrated the algorithm could enhance the successful ratio of the routing among the mobile nodes reduce the average routing delay.
