Performance Evaluation of DVMRP, ODMRP & PIM-DM Routing Protocol on the Basis of Quality of Service

چکیده
Multicasting is intended for group-oriented communication services. One particularly challenging environment for multicast is a Mobile Ad-Hoc Network (MANET) where, the network topology can change randomly and rapidly, at unpredictable times. As a result, several specific multicast routing protocols for MANET have been proposed. Multicast approaches can generally be categories into two: proactive and On-Demand. The proactive approaches pre-computed and maintains routes to all nodes, including nodes to which no packets are being sent. The on-demand approach creates the routes between nodes that are solely determined when they are explicitly needed to route packets. Multicasting protocols can also be categorized based on the structure used to forward multicast packets which are tree and mesh based. The uses of on demand routing approaches have been shown to have significantly benefits in terms of reducing the routing protocol’s overhead. Therefore, this paper focuses on performance of tree and mesh based multicast routing protocols over MANET. This paper, evaluates well alone multicast routing protocol DVMRP, ODMRP & PIM-DM under a wide range network condition & realistic scenario more a specifically the concern is to categorized a merit tree & mesh based protocol over various ranges of MANET scenario based on representative performance metric .The simulation environment Qualnet 5.0. As a result this work investigates the relative strength weakness and applicability of each protocol to diverse situation.

Performance Comparison of Mesh based and Tree based Multicast Routing Protocols in MANETs
Multicast routing is a key technology for modern communication networks. It sends a single copy of a message from a source to multiple receivers over a communication link that is shared by the paths to the receivers. This is especially appropriate in wireless environments where bandwidth is scarce and many users are sharing the same wireless channels. In particular, for WMNs, multicast can repr...

The MANETs is to extend mobility into the realm of autonomous, mobile and wireless domains, where a set of nodes form the network routing infrastructure in an ad-hoc fashion. The majority of applications of MANETs are in areas where rapid deployment and dynamic reconfiguration are necessary and wired network is not available. In ad-hoc networks, nodes are not familiar with the topology of their...

We present our experiences in implementing and validating the On-Demand Multicast Routing Protocol (ODMRP) in a real wireless ad hoc network testbed. ODMRP maintains a mesh for each multicast group to provide multiple alternate paths. Redundancy created by the mesh helps overcome frequent topology changes resulting from node mobility, channel fading, and interferences. The protocol does not mai...
