In this paper, the authors propose a receipt-free cooperation incentive scheme for multi-hop wireless networks. The nodes submit lightweight payment reports containing their alleged charges and rewards, and store undeniable security evidences. The fair reports can be cleared with almost no processing overhead. For the cheating reports, the evidences are requested to identify and evict the cheating nodes. Since cheating actions are exceptional, their scheme can significantly reduce the overhead of submitting and processing the payment data.
