Multicast Tree Formation and Analysis the Performance in AODV Protocol

Abstract

MANET applications has great benefits from multicast and apply in the fields where multicast performs effectively and efficiently. Multicasting is a technique which provides an important service for optimizing bandwidth consumption, throughput, and delay of distributed systems when number of users take participate in communication session simultaneously. On-demand routing protocols is used for the route establishment from source to destination only when it is required. AODV and DSR are the reactive routing protocols which uses flooding approach for establishing the route from source to destination. In this paper we propose an algorithm in which multicast tree is computed in network with the nodes having limited multicast capability and the problem of flooding is overcome with the same technique. The performance differentials are analyzed using varying simulation time. These simulations are carried out using the ns-2 network simulator. The simulation results shows that proposed technique is better than existing technique in terms of packet loss, delay and throughput.
