A multi-hop wireless network is a network in which a packet traversed in multiple successive wireless links to reach its destination. It is similar to mobile adhoc networks, but nodes in multi-hop wireless network are fixed. Multi-hop wireless networks can be deployed at less lost and it enlarges the coverage area with limited transmit power, enhance the spectral efficiency and network throughput. But the multi-hop wireless networks are vulnerable to different types of attacks. The selfish nodes in the multi-hop wireless networks do not relay other packets and by utilizing the cooperative nodes to transfer the packets to other nodes so that the cooperative nodes are overloaded due to the high traffic. In this survey, several payment schemes are suggested to identify the cheating nodes. The receipt-based payment scheme is one of the schemes in which the accounting center accumulates and organizes the credit account of all the nodes. Each node in the network typically submits indisputable proofs for the relaying packets to the accounting center to update their credit accounts. But the drawback in this method is high communication overhead and computational complexity. Specifically, in this survey different payment schemes are suggested and analyzed the performance.
