Abstract

A Mobile Ad-hoc Network (MANET) is composed of Mobile Nodes (MNs) without any infrastructure. Mobile Nodes self-organize to form a network over radio links. Multicasting can efficiently support data transmissions and thus is very suitable for MANETs. Implementing multicast routing protocols to MANETs leads to improve the consumption of bandwidth, reducing the cost of communication in the network and improving the efficiency. In this paper, we provide an overview of multicast routing mechanism especially in routing based on mesh and tree topology.

Abstract

The task of finding and sustaining routes in Mobile Ad-hoc Networks (MANETS) is an important factor in determining the efficiency of any MANET protocol. MANET characteristically is an autonomous system of mobile nodes connected by wireless links without any centralised infrastructure. The absence of fixed infrastructures and host mobility, thus network may experience rapid and unpredictable topology changes. Hence, routing is required in order to perform communication between the entire networks. There are several routing protocols namely proactive, reactive and hybrid etc. In this paper we will discuss the active research work on these routing protocols and its performance evaluation. To this end, we adopt a simulation approach, which is more suitable to this kind of analysis
