Stochastic Simulator For Estimating Delay In DTN Environment

Delay Tolerant Networks (DTN) very often suffers from route failures due to the store-carry and forward approach and also due to the mobility of nodes. The problem is delay at each node until the message carrying node doesn’t find the receiver node. This situation limits the applicability of traditional routing techniques which categorize lack of path as failure of nodes and try to seek for existing end-to-end path. Approaches have been proposed which focus either on epidemic message replication or on prophet routing previously known information about the connectivity schedule. We have considered that the protocol have the previous knowledge of routing and computed delay on the basis of replication on the nodes and on the basis of total time to transfer the packets from one node to other node. The proposed work prevents in large delays due to replications and the total time for sending the packets. Keyword DTN , PRoPHET, TCP/IP, AODV, DSR,
