Taking sanctioning seriously: The impact of sanctions on the resilience of historical commons in Europe

In their studies of collective exploitation of common-pool resources, Ostrom and other scholars have stressed the importance of sanctioning as an essential method for preventing overuse and, eventually, the collapse of commons. However, most of the available evidence is based on data covering a relatively small period in history, and thus...

Rewarding Good Behavior in Peer-to-Peer Networks

Large-scale human cooperation is vital to society. Designers and community facilitators of peer-to-peer networks are constantly investigating free-riding prevention measures for their platforms. Such schemes of rewarding good behavior remain a challenging problem in fully decentralized P2P networks. This work is a first attempt to integrate...

Free-riding Resilient Video Streaming in Peer-to-Peer Networks

Reducing Free Riding in Peer-to-Peer Systems with Supervised Teaming

Peer-to-peer technology has produced thriving communities in which peers contribute bandwidth to each other. However, when free riding occurs, these communities will not be able to sustain themselves without incentives to enforce this contribution. This thesis presents Supervised Teaming, a peer-to-peer transfer protocol that gives uploading...

Give-to-Get: Free-riding-resilient Video-on-Demand in P2P Systems

Centralised solutions for Video-on-Demand (VoD) services, which stream pre-recorded video content to multiple clients who start watching at the moments of their own choosing, are not scalable because of the high bandwidth requirements of the central video servers. Peer-to-peer (P2P) techniques which let the clients distribute the video content...
