Abstract:


Opportunistic Networking is one of the most extreme evaluation of multi-hop wireless network. In opportunistic networks the node mobility can create contact opportunities among nodes, which enable the mobile nodes to communicate with each other even if a route connecting to them never exists. As a result, nodes can physically carry buffered data while they move around the network area until they meet the forwarding opportunity. However, opportunistic routing requires sufficient amount of mobile nodes in order to satisfy carry-store-forward paradigm. The performance of this challenged protocol decrease when the number of mobile nodes decline. This paper proposes a novel routing technique to facilitate the mobile node routing in extreme sparse network called the rendezvous based routing. This proposed protocol can bridge the gap of space and time domain in opportunistic environment. The result of this paper shows that our proposed technique can increase the efficiency index defined as delivery ratio per average latency of very sparse opportunistic network environment.
