Modified Efficient Geographic Multicast Protocol in Multicasting Over Mobile Ad Hoc Networks for QOS Improvements
By the development of new network technologies, multicasting has become one of the important networking services. MANET (Mobile Ad hoc NETwork) a self-configuring infrastructure less network of mobile devices connected by wireless links. But, it is big challenge to implement the well-organized and scalable multicast in MANET due to the difficulty in group membership scheme and multicast packet forwarding over a dynamic topology. During recent years several multicast protocols have also been designed specifically for MANETs like ODMRP and MAODV. These protocols all follow the traditional multicast approaches, i.e. distributed group membership management and distributed multicast routing state maintenance.
