COOPERATIVE PACKET DELIVERY USING ENHANCED COOPERATIVE OPPORTUNISTIC ROUTING SCHEME (ECORS) IN MANET

Cooperative communication is an active area of research today. It enables the nodes to achieve spatial diversity, which leads to tremendous improvement in system capacity and delay. In this proposed system cooperative communication mechanism is used to determine a list of intermediate relay nodes that follows en-route to the destinations. Here, when data packets are broadcasted from a source node and the packets are received by a destination node along with the route. Cooperative communications which utilizes nearby terminals to relay the message transmissions also induces the non-cooperative nodes to participate in some opportunistic environments for achieving the diversity gains and to improve the efficiencies among the mobile nodes in wireless mobile ad hoc networks. The Enhanced Cooperative Opportunistic Routing Scheme (ECORS) which is based on light weight proactive source routing is used in this work to ensure the cooperation of participating mobile nodes in MANETs. This new protocol is used to easily identify the intermediate nodes and establishing the trusted routes. The comparative performance analyses among AODV versus ECORS are properly carried out and the better cooperative packet delivery ratio, increased throughput and decreased delay in packet delivery are achieved in this network simulation.
