A secure payment scheme, called as the Report based pAyment sChemE (RACE) is used in multi hop wireless networks to stimulate node cooperation, regulate packet transmission and enforce fairness. The nodes submit lightweight payment reports (instead of receipts) to the trusted authority to update their credit accounts and temporarily store the evidences. The report includes the session information. The trusted party verifies the payment by investigating the consistency of the report and clears the fair reports with almost no cryptographic operations or computational overhead. The nodes which do not pass or relay others' packets are called selfish nodes. But it makes use of neighbor or cooperative nodes to relay its packets.
