    ABSTRACT
    Delay Tolerant Networking (DTN) can be used as a way of communication when existing infrastructure is totally damaged or not possible to establish in the regions like military, disaster and fire fighting. It is most suitable to the application of disaster scenario because end to end path may not be available most of time and connectivity between rescue team member and survivors become opportunistic. Post disaster scenario where it is not possible to predict the movement of people because there is not real trace data available. Some authors represented mobility model in disaster scenario using which it is possible to generate movement pattern of rescue team members and survivors. One of the factors which affect the performance of DTN is design of routing protocol. Many DTN routing protocols have been proposed in the literature but their performance depends mainly on the application where it is used. In this paper, we explore the performance of five different routing protocols namely Epidemic, Binary Spray and Wait (BSnW), Spray and Focus (SnF), Encounter Based Routing (EBR) and PRoPHET. We have evaluated performance of these protocols in terms of delivery probability, overhead ratio, average delay and average hop count by varying buffer size, message size and number of messages per minute. Simulation is conducted using Opportunistic Network Environment (ONE) simulator.​
