Detection of Cheater Nodes Based On Evidences and Reports in MultiHop Wireless Networks

Abstract

A Secure Payment Scheme called as a Report-based payment scheme for multi-hop wireless systems to stimulate node cooperation, regulate package transmission, and enforce fairness. The nodes submit lightweight fee accounts (instead of acknowledgements) to the accounting center (AC) and temporarily being store undeniable security tokens called Evidences. The reports comprise the alleged charges and rewards without security verifications, for example, signatures. The AC can verify the payment by investigating the consistency of the accounts, and clear the fee of the fair accounts with nearly no processing overhead or cryptographic operations. For betraying accounts, the Evidences are requested to recognize and evict the betraying nodes that submit incorrect accounts. Rather than of requesting the Evidences from all the nodes participating in the cheating accounts, RACE can recognize the betraying nodes with requesting few evidences. Furthermore, evidence aggregation technique is utilized to decrease the evidence storage locality. Our analytical and simulation results show that RACE requires much less communication and processing overhead than the existing receipt-based designs with agreeable fee clearance delay and storage locality. Furthermore, RACE can secure the fee and accurately identify the betraying nodes without untrue accusations.
