Effective Multicast Communication using MSODRP over Dynamic Wireless Networks

-Group communications are important in Mobile Ad hoc Networks (MANETs). Multicast is an efficient method for implementing group communications. However, it is challenging to implement efficient and scalable multicast in MANET due to the difficulty in group membership management. Efficient Geographic Multicast Protocol (EGMP) uses a virtual-zone-based structure to implement scalable and efficient group membership management. A network wide zone-based bidirectional tree is constructed to achieve more efficient membership management and multicast delivery. EGMP has high packet delivery ratio, and low control overhead. But it has some delay. ODMRP gives less delay and better packet delivery it has the advantages of Usage of up-to-date and shortest routes, Maintenance and exploitation of multiple redundant paths, Scalability to a large number of nodes. SPBM gives the position based information for the packet transmission. Here the combination of these the protocol (MSODMRP) gives the high packet delivery, less delay and secure transmission.
