Author Name : Jayalakshmi G Naragund, R M Banakar
Abstract : Wireless mesh network (WMN) is used to develop techniques for guaranteeing end-to-end delay performance over multihop wireless communication networks. The aim of WMN is to provide seamless communication in large heterogeneous networks and between heterogeneous devices. According to the architecture of WMN, mesh cloud will allow scaling the network easily. Hence we are addressing WMNs as scalable networks. Routing protocols play an important role in increasing the performance of WMN as the size of network is scaled. Routing process is also affected by the type of communication, like unicast and multicast. Multicasting is eminent type of communiqué nowadays, due to its applications like Distance Learning, Access to Distributed Data Base and Teleconferencing etc. This paper proposes the multicast routing protocol for WMN. Multicast Ad hoc on demand Distance Vector (MAODV) is modified to support scalable WMN. MAODV creates bi-directional shared multicast trees for connecting multicast sources and receivers. In this research work authors briefly narrate the MAODV protocol and it is compared with unicast AODV. Using NS2 a simulation based performance evaluation is done by considering performance metrics, such as Packet Delivery Ratio (PDR), end-to-end delay, throughput, overhead and dropped packets. Results show that MAODV routing protocol throughput is 43% and PDR is 31% more than AODV. Bandwidth utilization is measured in terms of overhead; the MAODV is having 50% less overhead than AODV.
Keywords : Wireless mesh network, Multicast routing, Unicast routing and TCP/IP protocol stack.
