Abstract
In recent years' mobile ad hoc networks (MANETs), a group oriented services has one of the primary application classes. It supports such services that use multicast routing. Therefore it is required to design stable and an efficient routing protocol for MANETs to support better packet delivery ratio, minimum delays and decreased overheads. In this paper, a multicast routing protocol based mesh networks that finds stable multicast path from source to receivers is proposed. In this model only the nodes that fulfill the delay requirements can flood the JOIN-QUERY messages. The contributing nodes are assumed to follow M/M/1 queuing systems. The queuing systems contain maximum value for queuing and contention delay which can be evaluated as the ratio of maximum queue size over the service time in a node. This model enhances link stability with contention delay and queuing system. The stable routes are found based on selection of stable forwarding nodes that have high stability of link connectivity. The link stability is calculated by using parameters link received power, distance between neighboring nodes and link quality. The performance of the proposed model is simulated over a large number of MANET nodes with wide range of mobility with two well known mesh based multicast routing protocol. It is observed that the proposed model produces better throughput and reduced overheads.
