  • Collaborative multicast routing (CMR) for multicasting in unidirectional, hybrid, multi-tiered mobile wireless network
    Patent number: 8144708
    Abstract: The present invention provides a scalable and reliable collaborative multicast routing for multicasting in hybrid, multi-tiered, mobile heterogeneous wireless networks. It establishes a multicast tree, maintains the established route, detects and prevents most link breakage within the multicast tree by a neighboring node or the cooperation of the neighboring node, and enables merging of partitioned multicast trees of the same multicast group by nodes that participate in one of the partitioned multicast trees. The use of local nodes to collaboratively establish, maintain, recover, and merge the hybrid, multi-tiered mobile wireless networks that use heterogeneous set of mobile wireless nodes is the fundamental basis for the collaborative multicast routing scheme of the present invention.
