Abstract
A Mobile ad hoc network (MANET) is a collection of wireless mobile nodes forming a temporary network with-out using any existing infrastructure. Mobile Ad-Hoc is a dynamic, multi-hop and autonomous networks composed by wireless mobile nodes. MANETS are subject to rapid and unpredictable changes. MANETS are inexpensive wireless communication network. The mobility model represents the realistic behavior of each mobile node in the MANET. Routing Protocol for Ad-Hoc networks are typi-cally evaluated using simulations. In this paper, we compare the performance of On-Demand Multicast Routing Protocol (ODMRP) with the Adaptive demand driven Multicast Routing Protocol (ADMR) under different mobility models such as Random Way Point Model, Manhattan Model and Random Drunken Model. Using these models, performance metrics such as Packet Delivery Ratio, End-to-End Delay and Control Overhead are evaluated. ODMRP dynamically builds the route and manages the group membership. In ADMR, Multicast routing state is dynamically established and maintained only for active groups and only in nodes located be¬tween multicast senders and receivers. ADMR detects the high mobility without the use of GPS or other positioning system. The simulation result shows that the throughput of ADMR is higher than of ODMR at high mobility and ODMR is high at low mobility. End to end delay and control over head of ADMR is higher than ODMR.
