Analysis of BABEL and PUMA Protocol for Mobile Adhoc Networks (MANETS)

An adhoc network is a collection of wireless mobile nodes that forms a temporary network without any centralized administration. A short lived network just for the communication needs of the moment. It is an infrastructureless network. While early research efforts assumed a friendly and cooperative environment and focused only on problems such as wireless channel access and multihop routing. The main aim of this Research Paper is to present an overview of BABEL and PUMA protocols along with their respective advantages and disadvantages. Design of a suitable routing protocol is difficult for mobile ad hoc networks due to its inherent dynamism and frequent topology change. Multicasting is even more complex because it requires transmission of an information to various destinations at approximately same time, if possible. Active research work in this field has resulted in a variety of proposals based on tree or mesh structures. This Research Paper presents a state-of-the-art overview of multicast routing protocols Babel and puma for ad-hoc networks.
