A Trust Based Payment Scheme for Multihop Wireless Networks

S.Suganya,S.Dhivya,Y.Jenifer

I n a multihop wireless networks a trust based payment scheme is proposed for motivating node collaboration and for regulation of packetbroadcast. Every node submits align weight payment reports to the Accounting Center(AC) and stores an acceptable security tokens called Evidences. For every successful packet,diffusion would report a payment to the AC automatically. There by reports stability are verified to evaluate the payment,and clearsall the successful payment report without any cryptographic operations. Fo r e v e r y cheatingreport, submitted evidence is used to identify the occurrence of cheating in the payment reports. Insteadof reporting for every node transmission to the AC, a trust based payment scheme would provide a trust value to be fixed for every node. A higher trust value routes must be chosen for performing the packet transmission. Moreover, trust aggregation technique is used to reduce the trust packing area. Thi s t r u s t v a l u e entails very less communication and processing overhead than the existing report-based schemes. Thus the usage of micropayment is an actual execution of a payment scheme. Moreover,for every node,trust based scheme reduces the cheating node with an identification of abrupt trust value.
