Distance Based Angular Multicast Routing Protocol for Mobile Ad Hoc Networks (DA-MRP)

In Mobile ad hoc networks (MANETs), mobile nodes communicate with each other with the help of hello messages as there is no centralized infrastructure. Routing protocols in MANETs are mainly concerned with unicasting and multicasting. Design of an efficient multicast routing protocol is one of the major challenges of MANETs. Multicast routing protocol deals with the transfer of messages from a source to multiple destinations and it has become very popular nowadays. In this paper, we propose a multicast routing protocol (DA-MRP) for MANETs that includes the directional forwarding along largest distance from source to destinations. We analyze the performance and efficiency of our proposed protocol using simulator OMNET++. Our protocol aims at achieving reduced packet overhead, low network delay and high scalability in the network. Our protocol is mainly proved best in dense network.
