A Micropayment Scheme Encouraging Collaboration in Multi-Hop Cellular Networks
Proceedings of Financial Crypto 2003, 2003, La Guadeloupe, January.
abstract We propose a micro-payment scheme for multi-hop cellular networks that encourages collaboration in packet forwarding by letting users benefit from relaying others` packets. At the same time as proposing mechanisms for detecting and rewarding collaboration, we introduce appropriate mechanisms for detecting and punishing various forms of abuse. We show that the resulting scheme -- which is exceptionally light-weight -- makes collaboration rational and cheating undesirable.
