Design of efficient multicast routing protocol using limited flooding mechanism

Abstract

A Mobile Ad-hoc networks (MANETs) is composed of Mobile Nodes without any fixed infrastructure. Multicast routing in mobile Ad-hoc networks (MANETs) have many defiance due to implicit characteristics of the network such as node mobility, reliability, finite network resources etc. So, in this paper we have introduced a new scheme to improve the performance and efficiency of multicast routing protocols. Our proposed scheme is called multicast routing using limited flooding mechanism. This mechanism is integrated over MAODV which enhance the multicast routing efficiency. This mechanism manages the data packets flow based on delay characteristics of the contributing nodes. In proposed scheme only the nodes that satisfy the delay requirement can only flow the data packets from source node to a multicast receivers. The proposed scheme calculates the various types of delay such as transmission delay and propagation delay on each contributing mobile nodes to establish the multicast routes. This scheme is inspired by studied some implicit lacks of existing multicast routing protocols such as: weak robustness of dynamic topology, low reliability, low scalability, lack of QoS (Quality of Service) support, less packet delivery ratio and high packet delivery delay.
