A NEW APPROACH OF MULTICAST ROUTING PROTOCOLS IN MANETS BASED ON CBR (CASE-BASED REASONING) METHOD

Multicast routing protocols significantly increase the performance of the network using a new approach of group-orientedservices which become recently apparent for MANETs. Due to this reason several MANET-specific multicasting routingprotocols have been proposed. Although numerous challenges in designing multicast routing protocols in MANETs becomeostensible due to node mobility, contention for channel access, multi hop communications and dynamic topology,researchers tend to address such problems by designing simple, scalable and robust routing protocols. In this paper tried toexplore the existing On-Demand Multicast Routing Protocol (OMRP) with its limitation and propose a new approach ofCBR based multicast routing protocols without changing the basic structure of the protocol. Nodes with CBR based OMRPbecome autonomous by keeping track of previous route discovery experience to reuse back as a solution. This will reducechannel overhead and improves the scalability of the ad hoc network.Keywords: Mobile ad hoc networks (MANETs), Multicast Routing Protocols, and Case-Based Reasoning (CBR)
