Abstract:
Opportunistic Networks are a subclass of Delay Tolerant Networks (DTN), which aim at wireless data delivery in severely partitioned networks. There exist several protocols that route messages on a best effort basis. In most cases, the nodes copy and forward messages to nodes that are more likely to meet the destination. But, the major challenge is to design a routing protocol that offers the best tradeoff between cost (number of message replicas) and rate of successful message delivery. In this research paper, the tradeoff is being efficiently handled by using the concept of Google Pagerank like centrality to rank nodes in a network using social information. Unlike other nodes in the network, central nodes act as influential nodes to facilitate the message forwarding. Furthermore, to the centrality routing, a mechanism of message relay control is designed and linked to keep the network overhead ratio low. The proposed Centrality Based Routing Protocol (CBRP) with Message Relay Control algorithm was evaluated by simulations using the Opportunistic Network Environment (ONE) simulator. The results show that CBRP outperforms other typical routing protocols in Opportunistic Networks.
