A Data Transmission Strategy of P2P Live Streaming Media System

In this paper, an algorithm optimization is made with improved simulated annealing algorithm aimed at data transmission strategy of streaming media System in P2P networks. According with global layout, we have established a mathematic model for data transmission strategy of streaming media System in P2P networks named VMDTSA-P2P, which completely have considered the affection of both the out-bandwidth and the available time. We also optimize the solutions with improved simulated annealing algorithm. Compared with existing data transmission strategies, this improved algorithm accelerates the speed of new nodes choose the data provider from its partner nodes when there are lots of users and insures the solution of the data provider is approximate the best. Thus, the play delay of the streaming media System is decreased and the quality of video playback is increased. By realizing it in a simulated P2P system, the accuracy and the efficiency are both verified in the simulation.
