摘要：Multi-hop cellular networks (MCN) appear to be a promising combination of the dynamics of the mobile adhoc 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 behaviour would cause sharp degradation and negative impact on network fairness and performance. In this paper, we propose a fair and secure incentive mechanism to stimulate node cooperation in multihop wireless networks. Fairness is achieved by using credits to reward the cooperative nodes. To implement this charging policy efficiently and securely, light weight hashing operations are used in ACK packets to reduce the number of public-key-cryptography operations. Moreover, reducing the overhead of payment checks is essential for the efficient implementation of the incentive mechanism due to the large number of payment transactions. Instead of generating a check per message, a small-size check can be generated per route, and a check submission scheme is proposed to reduce the number of submitted checks and protect against collusion attacks.
