Reliable Routing Protocol in Delay Tolerant Networks

Abstract- Delay Tolerant Networks (DTNs) are supports data transfer in challenging environments where a fully connected end to end path may never exist between a source and destination. These networks deal with large transmission delays, frequently disconnected paths, high link & path error and limited resources.examples of this kind of networks are satellite communication, ad-hoc & sensor, vehicular networks. DTN routing protocols utilize the mobility of the nodes and buffering of messages, this makes is possible for a node to carry a message and in that way bridge partition in the network. It is also known as store-carry-forward. In this paper, we proposed reliable routing protocol in DTNs based on network coding-Multi Generation Mixing policy, that increase the reliability, while increasing data transmission delay as compared to the protocols with the best performance. Simulation of a network coding-based information delivery method in wireless networks which improves the network performance and reliability. Network coding is a paradigm to efficiently broadcast the data in wireless networks in which data flows coming from multiple sources are combined to reduce delay, and enhance robustness against node failures. Simulation results show that the proposed routing protocol Multi Generation Mixing Epidemic Routing Protocol (Epidemic_MGM) increase the Delivery Probability compare to the Traditional epidemic routing protocol
