On Secure VANET-Based Ad Dissemination With Pragmatic Cost and Effect Control

Abstract

Allowing commercial service providers (SPs) to promote their businesses, ad dissemination in vehicular ad hoc networks (VANETs) shows great application potential. In this paper, a VANET-based Ambient Ad-Dissemination scheme (VAAD) is proposed to support secure ad disseminations with pragmatic cost and effect control. VAAD provides an incentive-centered architecture for the involved parties to trade off their conflicting requirements regarding ad dissemination. Given realistic advertising effect and cost requirements of an SP, VAAD adopts a distance-based gradient ad dissemination algorithm to maximize the achievable ad effect by emulating the ad-posting patterns in the physical world. To facilitate vehicular nodes' participation in VAAD, efficient, secure, and privacy-preserving incentive cash-in is ensured to support financial transactions in VAAD. Thus, with proper cost and effect control, VAAD is a novel and comprehensive solution to secure ad dissemination in VANETs.
