Increased demand for wireless communication required efficient quality of communication. Nowadays, wireless communication ns where end-to-end connectivity from source to destination is a crucial task such as interplanetary networks, vehicular networks, underwater networks, etc…In order to address these issues, DTN (Delay Tolerant Networks) have been introduced which helps to enable the end-to-end connectivity between source and destination by using a store-and-forward mechanism. However, the connectivity and performance of conventional DTNs suffer from the issue of unreliable environments, high dynamics of nodes and power consumption. Moreover, security is also considered a challenging task in these networks. Thus, in this work we focus of these issues of DTN and introduce a novel hybrid approach which provides an efficient solution for relay selection, buffer and, trust management scheme, this scheme is called as Relay Selection Trust Management (RSTM) model for Delay Tolerant Networks. The performance of the proposed approach is compared with the existing techniques such as Epidemic routing, Game theory, and spray & waits approaches. The experimental results show that the performance of the proposed approach RSTM achieves better performance in terms of packet delivery, delay, communication. © 2019, World Academy of Research in Science and Engineering.
