A Simulation System Based on ONE and SUMO Simulators: Performance Evaluation of First Contact, Prophet and Spray-and-Wait DTN Protocols

摘要

In this paper, we investigate the performance of First Contact, Prophet and Spray-and-Wait 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 and 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 for PDR the Prophet protocol has better performance than other protocols. Considering RDR, the performance of First Contact and Spray-and-Wait protocols is better than Prophet protocol. For hop count, the performance of Spray-and-Wait protocol is better than other protocols. While for delay, the performance of Prophet protocol is better than other protocols.
