Abstract
In BitTorrent network, how to avoid free-riders is an in inevitable problem of improving BitTorrent performance. Using trust management is a trend of P2P transmission. We propose a combine trust management scheme, combining local trust value and trust value from neighbors to calculate a combine trust value. The combine trust value represents the spread of reputation in the BitTorrent network. Through the combine trust value, peers could recognize the free-riders. Experiment results prove that compare combine trust management scheme with local trust management scheme, the combine trust management could avoid more free-riders, thus has better download performance.
