摘要：

Delay/Disruption Tolerant Networks (DTN) can support data transmission under the challenging network conditions. And one of the most important protocol components for DTN is a routing protocol to improve the performance of transmission delay and delivery success ratio. In this paper, we propose the "Mobility Pattern based Routing (MPR)" algorithm that controls the total number of transferred message copies based on mobility patterns of mobile nodes. We consider a realistic "Levy walk" mobility pattern that has a super-diffusive property which well represents human mobility pattern. We implemented a DTN simulator using ONE simulator [91 for the proposed MPR algorithm and Levy walk mobility pattern. Simulation results show that Levy walk mobility pattern provides more accurate evaluation environment for DTN, and the proposed MPR enhances the routing performance of delivery delay and success delivery ratio under realistic mobility pattern.
