In Mobile Ad Hoc Networks (MANETs), Dynamic Source Routing (DSR)protocol suffers from different types of attacks,which mainly occur in route discovery.Currently,there exist various attack detection techniques for detecting these attacks. The existing attack detection techniques require security-related data that can be collected by forwarding nodes. However, the forwarding nodes might not be willing to collect security-related data due to overload, selfishness,low battery power, etc. This problem is still open and unsolved. We propose a micropayment-based incentive mechanism for security-related data collection in route discovery of DSR protocol.It allows the forwarding nodes to insert collected security-related data into control messages before forwarding them.The forwarding nodes request crediting their account by transmitting the received control messages to a deposit service center. The proposed incentive mechanism can not only constrain the amount of payment of a source node by preventing exceedingly forwarding RREQs, but also make each forwarding node obtain a reward as much as possible for the purpose of ensuring fairness.
