A Simulation System Based on ONE and SUMO Simulators: Performance Evaluation of Direct Delivery, Epidemic and Energy Aware Epidemic DTN Protocols

In this paper, we investigate the performance of Direct Delivery, Epidemic and Energy aware Epidemic 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). For the simulations, we used IEEE 802.11p standard, TwoRayGround Propagation Loss Model. We use Packet Delivery Ratio (PDR), Relay Delivery Ratio (RDR), hop count and delay as evaluation metrics. We compared the performance of three protocols and the simulation results show that the Epidemic protocol is better 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.
