Abstract

In the last few years research activity in delay/disruption tolerant networks (DTN) is growing and researchers have proposed various types of routing protocols. Those efforts formulate DTN to become the adequate solution for the challenged network environment. DTN architecture provides good performance in the intermittently connected Mobile ad hoc networks (MANET). Routing in DTN architecture is the key challenge because of the nature of MANET environment where the network is an opportunistic connected and topology is changing rapidly. In this article we analyze the performance of DTN-based routing protocols including our routing approach, History of Encounters Probabilistic Routing Algorithm (HEPRA) in terms of different aspects. We select well-known DTN routing protocols in our evaluation to demonstrate how those protocols act comparing to our approach, HEPRA. We continue developing our algorithm, HEPRA, to provide a detailed analytical as well as simulation-based study. Using simulation we considered in our analysis various factors such as number of nodes, buffer size, speed of nodes, time to live (TTL), movement models and transmission range.
