摘要: Cognitive radio, which enables dynamic access of under-utilized licensed spectrums, is a promising technology for more efficient spectrum utilization. Since cognitive radio the larger amount spectrum, it can be used to build wireless mesh networks with higher network capacity, and thus provide better quality services high bit-rate applications. In this paper, we study multi-source video on-demand application in multiinterface networks. Given request, find joint multi-path routing allocation session minimize its total bandwidth cost network, therefore maximize number sessions support. We propose both distributed centralized channel algorithms solve problem. Our not only increase maximum concurrent that supported but also improve each session's adaptivity mobility.
