Abstract
Abstract: Mobile ad hoc networks (MANETs) plays an important role in the communication in the networkmust be set up temporarily and quickly. Since the nodes move randomly routing protocols must bring strong andconstant to ensure successful packet delivery. Advantage of multicast routing is the ability to reducecommunication costs and saving the network resources by just a copy of the message over the sharedcompound. Several destinations Based on the data delivery structure can multicast routing protocols are dividedinto two groups is a tree-based and other mesh-based. Tree-based protocols have high efficiency and lowconsumption of more bandwidth and may have poor robustness, since only one connection between two nodesexists. Like a tree based multicast routing protocol, MAODV (Multicast Ad hoc On-demand Vector) shows anexcellent performance in lightweight ad hoc networks. Since the load on the network increases, QoS (Qu ality ofS ervice) degraded. I n this paper, we summarize the effect of network load on MAODV protocol and anoptimized protocol MAODV-BB propose (Multicast Ad hoc On-demand vector with backup Branches), therobustness of the MAODV protocol improved by the combination of advantages of tree structure and the gratingstructure. It can not only update shorter branches, but also build a multicast tree with back-branches. MAODVBBprotocol improves the network performance over conventional MAODV in heavy load ad-hoc networks.
