Performance Analysis of Scalable Multicast Communication over Ad Hoc Networks

Abstract MANET based applications can be used in real time environment but their performance depends upon the various factors i.e. behavior of the routing protocol, quality of wireless links, network size, node density, mobility and transmission range, etc. In case of group communication, a multicast routing protocol should be able to provide an acceptable level of service in a network with a large number of nodes. It is also very important to take into account the nondeterministic characteristics (power and capacity limitations, random mobility, etc.). Routing protocols may use Proactive approach, Reactive approach or Hybrid approach for routing purpose and there is a need to explore the impact of scalability using these approaches. In this paper, we will investigate the behavior of multicast routing protocols with the various scalable factors, i.e. Packet size, Node density, Sender density under the constraints of Throughput, PDR and Routing Load etc.
