Abstract—It is proposed to analyze the usefulness of Bandwidth Reservation Protocol (BRP) for mobile ad-hoc networks in improving the quality of service (QoS). There are two types of bandwidth reservation protocols namely, priority based and scheduling based. In this simulation the priority based bandwidth reservation protocols are used. These are Fair End-to-end Bandwidth Allocation (FEBA) and Priority based Bandwidth Reservation Protocol (PBRP) algorithms. PBRP protocol consists of two phases namely Bandwidth Request phase and Bandwidth Reply phase. In the former Phase, a Bandwidth Request (BREQ) message is forwarded from the node that requests the admission of a new traffic flow to its destination. In the later Phase, a Bandwidth Reply (BREP) message proceeds backwards, hop-by-hop, from the destination node to the node that originated the request along the path laid down by the corresponding BREQ message. The destination node precedes the reply according to the priority of traffic classes and reserves the bandwidth on the reply path. By simulation results, it is found that the use of these protocols achieve high bandwidth utilization and throughput with reduced delay. The simulation is done on mesh based On Demand Multicast Routing Protocol (ODMRP) by using QUALNET 5.0.
