Abstract:
The different start video broadcasting is a new approach to improve the service of P2P video streaming applications. This approach allows unpunctual users to view broadcast programs from the beginning during server broadcast time. This paper proposes the non-cluster and cluster model for different start video broadcasting. The buffer management and mathematical model are proposed to estimate the performance of non-cluster and cluster model. These models are based on an application layer MESH network. These models are composed of five processes: peer join/leave, peer exchange information, peer selection, buffer organization and segment scheduling. The proposed models are simulated and verified by using NS-2. Moreover, the mathematical model is proposed to evaluate the performance metrics of server load, peer load, control message and buffer size. The results show that (i) the unpunctual users with different joining time are able to view the first video frame, (ii) the video server load is reduced drastically, (iii) the peer load is also reduced, (iv) the number of control messages exchanged between the nodes is reduced, and (v) the buffer size is constant. Moreover, the performance of cluster model is better than the non-cluster model.
