A Secure Payment Scheme in Multihop Wireless Network Using Shortest Reliable Routing

Abstract: In multi-hop wireless networks, nodes traffic is usually relayed through other nodes to the destination. Multi-hop relaying can enable new applications and enhance the network performance and deployment. Moreover, in developing or rural areas, multi-hop wireless networks can be deployed more readily and at low cost. A secure payment scheme in MWN using SRR is a report-based payment scheme for multihop wireless networks to stimulate node co-operation, 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 store the evidences. The nodes which do not pass or relay others packets are called selfish nodes. But it makes use of neighbor or co-operative nodes to relay its packets. This degrades the network connectivity and fairness. The nodes submit lightweight payment reports (instead of receipts) to the accounting center (AC). The AC can verify the payment by investigating the consistency of the reports, and clear the payment of the fair reports with almost no processing overhead or cryptographic operations. For cheating reports, the evidences are requested to identify and evict the cheating nodes. Then these reports are saved in TP. These reports can be used in future communication to select reliable cheater free route.
