Hypercube based Team Multicast Routing Protocol for Mobile Ad hoc Networks

In this paper, a novel multicast routing protocol namely Hypercube based Team Multicast Routing Protocol (HTMRP) has been proposed to address the scalability in mobile ad hoc networks. In HTMRP team multicasting is proposed where the multicast group does not consist of individuals rather, member teams. This mechanism is common in ad hoc networks to accomplish collective tasks such as emergency recovery, battle field where team affinity model exist when the member teams has a common interest. In MANET the link failures due to mobility is a big concern and is addressed in HTMRP by incorporating a logical hypercube model. The HTMRP also has a mesh layer on top of the hypercube for effective fault tolerance. In addition to scalability, HTMRP also guarantee the new QoS requirements namely high availability and good load balancing by incorporating team, hypercube and mesh tiers. The HTMRP has been simulated and extensively analyzed for scalability, delivery ratio and control overhead. The results show that HTMRP provides better performance for the above evaluation parameters than the existing multicast routing protocol.
