Abstract: With the development of wireless sensor networks technologies, network model tends to be dynamic, nodes in networks become mobile. It brings new challenges to routing algorithms. This paper introduces the Dynamic Leaves Tree(DLT) network model, presents the DLR routing algorithm used in the dynamic network without localization information. The DLR routing algorithm includes path-similarity computation and optimal path selection. Simulation results show that the DLR routing algorithm can guarantee more than 90% communication reliability in dynamic networks.
