In peer-to-peer video-on-demand (P2P VoD) streaming services, a video server load is reduced by peers who cache data of the viewed videos and send these data to other peers instead of the video server. Although FIFO is typically used as the caching algorithm, it is not efficient for using upload bandwidth of the peers because the peers can cache the data of unpopular videos and cannot be requested...
In this paper, we investigate the performance of centralized cooperative positioning algorithms. Compared to traditional positioning algorithms which solely exploit ranging information from anchor nodes, cooperative positioning additionally uses measurements from peer-to-peer links between the users. Since we are proposing a centralized architecture, all information has to be collected at a central...
Volunteer computing, sometimes called public resource computing, is an emerging computational model that is very suitable for work-pooled parallel processing. As more complex grid applications make use of work flows in their design and deployment it is reasonable to consider the impact of work flow deployment over a volunteer computing infrastructure. In this case, the inter work flow I/O can lead...
