A Convergence Scheme for Digital Video/Audio Broadcasting Network and Broadband Wireless Access Network

This paper introduces a convergence scheme for digital video/audio broadcasting (BCT) network and broadband wireless access (BWA) network. This convergence scheme supports the architecture based on both PMP topology and mesh topology. It works in the mode of time division with full spectrum multiplexing. Its frame length, BCT time-slot length and BWA time-slot length are adaptive to the arrival traffic and the whole network performance. Then the transmission and the process delay of the token and the performance of the network were analyzed. The main method used is based on M/G/l queue with vacation and time-limited service. The generating function and the mean values for the traffic load distribution in BCT BS and BWA BSs were given. Then it was simulated on the self-similar traffic background and compare with the fixed time-slot allocation scheme. This scheme can reduce the Hurst parameter in some extent.
