Familiar route retrieval for multicasting in MANETs

In the recent days, Mobile ad hoc networks (MANETs) are used extensively for applications that require mobility while routing, more importantly for emergency and military operations. Routing information to nodes without a fixed infrastructure and with dynamically changing infrastructure is one of the greatest challenges. Multicasting is a more frequent requirement for such defense operations, which adds on to the level of difficulty while routing. In order to overcome this challenge, a couple of protocols exist in the literature providing various solutions to delivering data to multiple destinations at mobility. However, these strategies are either of greater complexity or the cost is high. In this paper, we propose Familiar Route Retrieval for Multicasting (FRRM) in MANETs to use the route familiarity of nodes efficiently to construct routes to destinations. The performance of this algorithm is analyzed using the simulations in the network simulator.
