Abstract: | Performance of multicast routing protocol in mobile ad hoc networks is mostly characterized by underlying forwarding structure.
Currently, general structures based on tree/mesh based scheme cannot handle with transmission efficiency, robustness to dynamic
topology, scalability, and load balancing functionalities at the same time. To handle above key performance factors concurrently,
we propose a new virtual backbone architecture for multicast, which is based on hierarchical hypercube structure. Due to the
natural properties of hypercube structure, we can achieve efficiency, robustness and load balance in mobile ad hoc networks
where links are frequently broken owing to nodes’ free immigration. Furthermore, scalability problem is naturally resolved
by hierarchical structure. Finally, through simulation results, we have proven good scalability by demonstrating that our
structure can provide higher packet delivery ratio with low control overhead and better scalability than tree/mesh based scheme
without regard to the number of group members. |
