Secure Multicast Routing in MANETs for PBM Protocol

Free registration required

Executive Summary

A Mobile Ad-hoc NETwork (MANET) consists of Mobile Nodes (MNs) without any centralized authority. Mobile nodes form a network over radio links due to its infrastructure less environment. Multicast routing plays a significant role in MANETs. Due to its features, such as dynamic network topology, limited bandwidth, and limited battery power, routing in MANETs becomes a tedious task. In the presence of malicious nodes, the MANET is vulnerable to various kinds of attacks. The MANET protocol is found to be more vulnerable due to the lack of centralized authority and also due to its dynamic nature. Position Based Multicast (PBM) protocol does not require any distribution structure and it avoids flooding of control packets.
