An Interactive Charge Scheme with Reward and Non-repudiation

Recently, Wireless Mesh Network (WMN) has been used in constructing the city wireless networks. A fair charge scheme is critical for the widely application of the WMN. In this paper, we propose a charge scheme, which not only provides an undeniable bill for users and Wireless Internet Service Providers (WISPs), but also encourages users to forward packets. Furthermore, the least mean square error is first used to deal with the disputes between users and WISPs in our scheme. Then the analysis of security shows that our scheme can resist many attacks, such as over route and flow temper. Finally, a simulation is performed to demonstrate the efficiency and effectiveness of our scheme.
