A SURVEY ON VARIOUS MULTICAST ROUTING PROTOCOLS WITH ANDWITHOUT CROSS LAYER TECHNIQUES IN MANET

MANET is the wireless, infrastructure-less, continuously self-configuring network which plays an important role in the point-to-point communication and multipoint communication. Since unicast routing suffers from certain drawbacks, the Multicast Routing is introduced for the efficient and secured communication but it does not guarantee QoS. The Cross-Layer Multicast Routing is later introduced to increase the Quality of Services and for the effective communication. By using the CLMR Protocols, we can elite the information from multiple layers and these can also be used to increase the performance of overall network. The CLMR uses several protocols which will increase QoS and increase the signal strength when compared to the nCLMR. This paper presents the survey based on various multicast routing protocols with cross layer and without cross layer techniques in MANET
