BarterCast

BarterCast is a protocol to exchange the altruism levels of peers. Altruism is defined as the amount of uploading versus downloading of a person. The goal is to create incentives for cooperation. (See IncentiveSystems for an overview of other incentive mechanisms.)

Paper ideas

• Expression and dataset for barter partners per swarm (100+)
• Expression and dataset for number of downloads per user (1000+)
• Expression and dataset for download behavior of a community (10000+)

Source of info

Bittorrent crawl
Tribler crawl
Community crawl
P2PSimulator

Key research challenges

• Unavailability of information due to: using 1st hand info only and peers unreliability
• Overhead of sending to everyone, for instance, at the cost of 250 Bytes when giving out 10MByte.
• Bootstrapping into this collective rep sys.
