Bandwidth Trading in Unstructured P2P Content Distribution Networks

An Auction Based Distribute Mechanism for P2P Adaptive Bandwidth Allocation

“…In the case of dynamic pricing [7]- [10], the network adapts prices as the traffic load changes. In auction-based pricing schemes [11], [12], users attach a bid to each packet indicating the willingness to pay for the delivery of the packet, and the network serves packets in descending order of their bids.…”

Cooperation and fair resource allocation in communication networks

“…These systems differ from those examined in [1,10,15,16,[18][19][20]25,31], in that the contributions (uploads) of each peer have a direct negative impact on his download performance. Therefore, each peer would rather exploit his full capacity only for his own downloads, in order to maximize his utility.…”

“…The incentives used in previous work [1,10,15,16,[18][19][20]25,31] cannot be effective or even apply to single link capacity peers, as we explain in the following. Schemes in [1,8,10,20] do not reckon quality of service issues; the different quality of service offered and received or the different upload capacities and needs of the peers are not considered in the allocation decisions.…”

“…However, several studies [25,31,35,36] exhibited that BT's reciprocation policy (i) fails to prevent unfairness across peers in terms of volume of content served, (ii) is vulnerable to strategic clients and (iii) fails to shield the system from misbehavior. That is why there were several studies that proposed improvements over it [31,35,[37][38][39].…”

“…Finally, neither BitTorrent nor the proposed improvements over it [24,31,35,[37][38][39]42], support an algorithm to dynamically determine how peers over single capacity-limited link systems should allocate their capacity among their uplink and downlink streams. Therefore BT peers' performance is critically based on their arbitrary decisions as we will see in section 6.3.3.…”
