Multicast Routing Protocols in Manets
Sending multiple copies of packet to different nodes is called Multicasting. Wired and infrastructure-based wireless networks are supported by many multicast routing protocols. But, applying this concept in Mobile Ad hoc wireless NETworks (MANETs) is a big challenge. Problems in ad hoc networks are the scarcity of bandwidth, short lifetime of the nodes due to power constraints and dynamic topology due to the mobility of nodes. These problems put in force to design a simple, scalable, robust and energy efficient routing protocol for multicast environment. In this paper, the authors will discuss different multicasting routing protocols for mobile ad hoc networks and their deployment issues.
