A simulation system based on ONE and SUMO simulators: Performance evaluation of different vehicular DTN routing protocols

摘要

The advances in next generation network and IoT have provided a promising opportunity to resolve the challenges caused by the increasing transportation issues. In this paper, we investigate the performance of different routing protocols in a Vehicular Delay Tolerant Network (VDTN) crossroad scenario. The mobility patterns of vehicles are generated by means of SUMO (Simulation of Urban Mobility) and as communication protocol simulator is used ONE (Opportunistic Network Environment). We use Packet Delivery Ratio (PDR), Relay Delivery Ratio (RDR), hop count and delay as evaluation metrics. We compared the performance of six protocols and the simulation results show that for PDR the Epidemic protocol has better performance than other protocols. Considering RDR and hop count, the performance of Direct Delivery protocol is better than other protocols. While for delay, the performance of Epidemic protocol is better than other protocols.
