The Routing using Prophet Protocol in DTN based on Fuzzy mechanism

Delay Tolerant network is very large and sparse network compared to simple MANET .When two mobile node comes to each other within a range and exchange the information these scenario is called “contact� in DTN. Here in DTN end to end connectivity is not possible because of varying of contact time and very large network area. So the ordinary routing protocols of MANET like OSR, DSDV are not usable for DTN. Due to different nature of network DTN require some new protocols which can provide store and forward mechanism. Today DTN has large set of protocols like Epidemic, Spray and wit, PropHet, Fuzzy logic based and other more .In this paper we combine both the best performing protocol named Prophet and Fuzzy based routing and try to find better protocol compared to existing . Our proposed method transfers messages based on Probability and in inner logic it uses the fuzzy mechanism to priorities the message. This protocol gives good result in terms of average latency and delivery probability.
