An auction based seeder incentive algorithm for multi-torrent file systems

This paper investigates the problem that the current multi-torrent file systems lack incentives for seeder nodes, and suggests that practical multi-torrent file systems are very common, thus a good environment for seeder incentive is created; The tit for tat (TFT) incentive mechanism aims to maximize the download speed without considering the importance of seeder, so it can not be used in seeder incentive. On the basis of this, it presents an auction based seeder incentive algorithm (ABSI): first the seeder runs an auction for its bandwidth, then the leechers send their bids to the seeder, and the seeder decides how to allocate the bandwidth. The effectiveness of the ABSI and the download time of the system are also analyzed. The experiments showed the benefits of the approach.
