Design and Performance Analysis of Routing Protocols for Delay Tolerant Networks

Many of the researchers have done great effort in the field of Delay Tolerant Networks (DTNs). In this paper, all the major routing protocols (first contact, direct delivery, epidemic, prophet, max-prop and spray and wait routing protocols) are likewise investigated by varying the nodes traffic and buffer size. It is obvious from the outcomes shown that no one routing protocol is adequate for all the circumstances and diverse situation. Moreover, as the node traffic increases, Epidemic performs worst in case of Network Overhead. Additionally, as the node traffic increases, Prophet routing protocol performs better. So as to assess the performance, delivery probability ratio, network overhead ratio, avg. latency, avg. hop count and avg. buffer occupancy metrics are utilized.
