With the development of smart-phone devices, media stream transmission is bound to make wireless network communication resources that are in short supply cause greater pressure. Due to the user's move in the media stream transmission process in the mobile wireless network, it may be possible to lead to the following questions: the established connection is interrupted; the effect in data transmission structure becomes poor or invalid; wireless connection changes more frequently. All these problems will directly result in the QoS of media stream transmission. Back pressure algorithm is a control method which is firstly proposed by Tassinlas and Ephremides in the control theory. We choose back pressure algorithm as the basic research method of mobile media stream transmission because of the conclusion that back pressure algorithm can make the network load balance and maximize network utilization. According to the above problem, the article proposes the back-pressure algorithm guaranteeing deadline, and the proposed algorithm can well guarantee deadline of packet transmission. It not only can remove the packets which are redundant or staying too long time in the network, but also can make network throughput optimal. And in order to speed up the network's convergence speed and improve user's satisfaction index. We proposed cluster-based back pressure algorithm guaranteeing deadline.
