Threat on incentive based earning in VANET

Intelligent Transport System (ITS) provides several smart transportation solutions. The building block of ITS is Vehicular Ad Hoc Network (VANET). VANET supports and improves the travel experience by leveraging its services through applications. Safety, warning and infotainment are key applications supported by VANET. Infotainment applications are gaining popularity in the Internet based application domain. Advertisements are one of the forms of infotainment messages. Drivers who are vehicle bound play pivotal role in distributing these advertisements. Advertisement distribution promotes additional earnings to the drivers in the form of incentive. For every advertisement sent, the sender earns an incentive. The greed of earning incentives drives the nodes to become malicious and thus, it hoards incentive. These malicious nodes prevent other nodes from earning incentive. Thus, it poses a threat for promoting fair earning among all the nodes in the network. In this work, we have identified such malicious nodes which are greedy and hoards incentives thus prevents non-malicious nodes in the cooperative network in earning fair amount of incentives.
