A Survey on Infrastructure less Multicasting Routing Protocols in Mobile Adhoc Networks
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 5
Abstract
A Mobile Ad hoc Networks (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Mobile Ad-hoc Network (MANET) routing protocols facilitate the creation of such networks without centralized infrastructure. Hence, routing paths in mobile ad hoc networks potentially contain multiple hops, and every node in mobile ad hoc networks has the responsibility to act as a router. This paper is a survey of infrastructure less multicasting routing protocols in mobile adhoc networks. Ad-hoc OnDemand Distance Vector Routing (AODV) protocol is capable of unicast, broadcast, and multicast communication. Unicast and multicast routes are discovered on- demand and use a broadcast route discovery mechanism. The core assisted mesh protocol is introduced for internet multicasting. CAMP use cores only to limit the traffic needed for a router to join a multicast group. ODMRP is a mesh-based, rather than a conventional tree-based, multicast scheme and uses a forwarding group concept; only a subset of nodes forwards the multicast packets via scoped flooding. It applies on-demand procedures to dynamically build routes and maintain multicast group membership. PUMAProtocol for Unified Multicasting through Announcements is another mesh-based multicast protocol. The protocol uses a single control message, a multicast announcement that is exchanged periodically by each network node. One of the purposes of multicast announcements is to elect a core member for the group and to ensure that all nodes in the network have a path to the core.
