Delay Tolerant Network is emerging and competing research area, in an era where the crowning aim is to provide ubiquitous connectivity, even in diversified regions. In applications of delay tolerant network, secure and energy efficient routing is an important issue in homogeneous and heterogeneous network. Designing a foolproof routing protocol providing security with energy efficient nature of delay tolerant network is a challenging task. Routing with minimum bandwidth and limited energy consumption is a challenging issue thereof. Many routing protocols have been proposed in the literature. However, most of these protocols works in a homogeneous environment. Most of them fail to utilize bandwidth effectively because of broadcasting. Broadcasting results in increasing routing overhead and consumes bandwidth in a large amount. This research work aims at identifying the methods and tools for evaluation of Delay Tolerant Network (DTN) routing protocols. The primary goal of this research is to design and implement direction aware routing protocol for delay tolerant heterogeneous network. Design and experimental evaluation of the proposed protocol is done heterogeneous environment. This proposed SEDAR found to be efficient than most of the other well known DTN protocols proposed earlier.
