Abstract: In multihop cellular networks mobile nodes usually transmit packets through intermediate mobile nodes for enhancing performance. Selfish nodes usually do not cooperate which has a negative effect on the network fairness and performance. A fair, efficient and optimal incentive mechanism has been proposed to stimulate the mobile node’s cooperation. Hashing operations are used in order to increase the security. Trivial Hash function has been used to improve end-to-end delay and throughput. In addition Cyclic Redundancy Check Mechanism has been employed to identify the irrational nodes that involve themselves in sessions with the intention of dropping the data packets. Moreover, to reduce the collision at the Accounting Center a Border node has been entrusted the task of submitting the checks using a digital signature.
