Establishing stable and reliable routing protocol in multihop wireless networks

In multihop wireless network, selfish nodes do not forward other nodes packet and take advantage of cooperative nodes in relaying their packets. In this paper, we propose payment and trust based system which include node reputation value also as a parameter to establish stable and reliable routes in multihop wireless networks. The payment system uses credit values to reward the honest nodes that relay packets successfully and to charge the nodes that send packets. The trust system is used to calculate the reliability of nodes in terms of trust value. Node reputation values are numeric value and the trustworthy node must have node reputation as equal or above 10. In the proposed system the routes in the multihop wireless networks are established such that the traffic directed to highly trusted nodes which have high node reputation and energy value to minimize the probability of breaking the routes.
