Comparing Different DTN Routing Protocols in a Dense Deployment Scenario with Realistic Mobility Trace: Comparing Different DTN Routing Protocols in a Dense Deployment Scenario with Realistic Mobility Trace
In this paper we propose the usage of Delay Tolerant Networks (DTNs) in dense deployment scenarios where infrastructure access is not available or to reduce the traffic load from congested infrastructure networks for non-time critical applications. The purpose of this paper is to evaluate and compare the performance of different DTN routing protocols in such scenarios where realistic mobility trace is used. The performance is analysed using the metrics of delivery probability, overhead ratio, average latency, average number of hops and average buffer time. The simulation results show that DTN is a good solution to improve the network performance by reducing the traffic load in infrastructure networks and epidemic protocol is the most suitable routing protocol for realistic dense deployment scenarios
