Multi-hop Cellular Networks (MCN) appear to be a promising combination of the dynamics of the Mobile Ad-hoc NETworks and the reliability of the infra-structured wireless networks. In MCN, the mobile nodes usually depend on other packets to improve network performance. However, there are some selfish users who are reluctant to act as packet relays in order to save their own resources. Such non-cooperative behavior would cause sharp degradation and negative impact on network fairness and performance. In this paper, the authors propose a fair and secure incentive mechanism to stimulate node cooperation in multihop wireless networks.
