Delivery Delay and Distribution in DTN using Probabilistic Routing of Packets

Delay Tolerant Networks(DTNs) are new as well as promising developed research in network research areas. Delay Tolerant Networks are those networks end to end path may not be possibly established among nodes instantly or may be remain absent for a long duration. The purpose of this study was to survey about the DTN routing protocols each of which aiming at maximizing the average delivery probability as well as minimizing the communication overhead, reducing the delivery latency, as well as energy consumed by the routing protocols during the process of delivering the messages with in the network. Hence, the performance of these routing protocols will be calculated using the simulator called NS2 Network Simulator2 which is peculiarly used for simulation of routing protocols.
