Abstract

Delay Tolerant Networks (DTNs) enable communication in challenged environments where end to end connectivity may not exist at some intervals. DTNs use store, carry and forward paradigm for delivering the message from one node to other node. Routing in DTNs is considered a challenging task because of the frequent disconnections and short contact durations. In present paper we evaluate the performance of some popular routing protocols used in DTNs based on characteristics like delivery probability, delivery latency and overhead ratio. Evaluating the performance of routing protocol requires suitable simulation tool so that the parameters used in simulation may be varied widely and the evaluated performance gives the result closer to the real world scenario. We used ONE (Opportunistic Network Environment) simulator for our simulation for providing a comparative analysis of performance of routing protocols.
