Abstract:

Based on the movement model similarity evaluation scheme (MMSE), a movement range oriented forwarding and dynamic multi-copies routing protocol (MROFDM) was proposed in vehicular delay-tolerant networks. With the si-milarity among the movement models and the local real-time information of vehicles, this protocol sended packets to the movement scope of destination node. At the same time, copy equilibrium strategy was used to dynamically adjust copy number of different types of packets. MROFDM with some existing multi-copies routing protocols were compare in simulation. The simulation results verify the performance advantage of MROFDM, and show the adaptability of MROFDM with different proportions of movement models.

Key words: delay-tolerant networks, vehicular networks, movement model, multi-copies routing
