The BitTorrent (BT) file sharing protocol is very popular due to its scalability property and the built-in incentive mechanism to reduce free-riding. However, in designing such P2P file sharing protocols, there is a fundamental trade-off between keeping fairness and providing good performance. In particular, the system can either keep peers (especially those resourceful ones) in the system for as...
The BitTorrent (BT) file sharing protocol is popular due to its scalability property and the incentive mechanism to reduce free-riding. However, in designing such P2P file sharing protocols, there is a fundamental "tussle" between keeping peers, specially the more resourceful ones, in the system for as long as possible to help the system achieve better performance and allowing peers finish...
In this paper, we present the mathematical analysis of two important performance measures for a BitTorrent (BT) like P2P file sharing system, namely, average file downloading time and file availability. For the file downloading time, we develop a model using the "stochastic differential equation" approach, which can capture the system more accurately than some previous approach and can capture...
