A Survey on Energy Efficient Multicasting in Ad Hoc Networks

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 paper presents a state-ofthe-art overview of multicast routing protocols for ad hoc networks. We believe that this survey will be a great source of information for researchers in ad hoc networks. Keywords— Ad hoc networks, Energy efficiency, Multicasting, Mesh, Tree.
