Timely scheduling algorithm for P2P streaming over MANETs

A segment scheduling algorithm for Peer to Peer (P2P) Video-on-Demand (VoD) streaming services is necessary to a mobile adhoc networks (MANET). In order to maximize the received number of segments; Most of the previous research efforts have focused on a greedy approach to utilize the all available network bandwidth. However, the greedy approach will waste the network bandwidth and buffer capacity of devices/peers in transmitting and storing segments whose playback deadline is far from met. Moreover, the performance of greedy approach decreased due to many inherited limitations of MANET such as peer mobility and peer interactions. In this paper, a distinct approach to address the above problems is adopted by scheduling evenly the segments of the P2P VoD streaming services transmitted into a MANET based on the playback-rate of the services. On the other hand, it schedules the segments from the peers with less bandwidth consumption to the network for further saving the limited bandwidth. Further, it is adaptive to host mobility and peer interaction. Extensive simulation illustrates the effectiveness of the proposed scheme. It is shown that the proposed scheme has 10.2% improvement in admission rate, and 7.6% improvement in successful receiving rate over the greedy approach.
