K-Tree: A Multiple Tree Video Multicast Protocol for Ad Hoc Wireless Networks
Source: Reed Elsevier
In this paper, the authors address the problem of video multicast over Ad hoc wireless networks. Multicasting is an efficient means of one-to-many communication and is typically implemented by creating a multicast tree. Video multicasting demands high quality of service with a continuous delivery to receivers. However, most of the existing multicast solutions do not guarantee this because they are not resilient to mobility of the nodes and do not exploit error-resilient nature of recently available video coding techniques. Uninterrupted video transmission requires continuous reachability to receivers which emphasizes the usage of path-diversity. Hence, they propose a multiple tree multicast protocol which maintains maximally node-disjoint multicast trees in the network to attain robustness against path breaks.
