Abstract

OPPNETs (Opportunistic Networks) are wireless networks that have sporadic network connectivity, thus rendering the existence of instantaneous end-to-end paths from a source to a destination difficult or impossible. Hence, in such networks, message delivery relies heavily on the store-and-forward paradigm to route messages. However, limited knowledge of the contact times between the nodes poses a big challenge to effective forwarding of messages. In this paper, EBR (encounter based routing) is proposed that focuses on algorithm to measure contacts between nodes and measure most favorable node. The contact is calculated between two nodes when they come in range of each other. The aim of proposed scheme is to reduce replication of messages. The proposed mechanism is implemented using ONE simulator. Simulation results show that proposed mechanism has less message delay, less replication of messages and less average buffer time.
