Traditional routing protocols e.g. TCP/IP, AODV cannot be configured in environments where end-to-end path is not stable due to network partitioned, dynamic topology changes and node mobility. Delay Tolerant Network (DTN) has emerged as a technology by which the communication architecture is formed through intermittently connected mobile nodes. These networks are categorized as opportunistic since further availability of connections cannot be predicted. Thus, the routing protocols transmit the multiple copies of each message around the connected nodes. Each node then carries this message copy in its buffer until the transmission opportunity arises. This hop-by-hop mobility of message(s) makes the quick progress towards destination.
