IPAD: Intelligent Parking-Assisted Ads Dissemination over Urban VANETs

Advertisement dissemination via vehicular ad hoc networks (VANETs), fuelled by commercial interests, has attracted tremendous research efforts lately. However, the existing ads dissemination schemes could either incur a high operational overhead in inter-vehicle communication or lead to a substantial capital overhead of constructing roadside infrastructure. To reduce the aforementioned costs, we propose IPAD (Intelligent Parking-assisted Ads Dissemination), which taps into the unused resources (e.g., wireless device, rechargeable battery, storage capability, on-board computer chip) offered by roadside parking in urban areas to facilitate ads dissemination to mobile vehicles. Our proposed IPAD scheme is substantiated with a novel architecture, which is cost saving and could support large scale ads dissemination. To realize efficient ads dissemination over this artitecure, we put forward an effective routing scheme to distribute each ad to appropriate roadside parking and introduce the pub/sub scheme into the last stage of ads dissemination. Finally, we investigate IPAD through theoretic analysis and simulation. The numerical results obtained verify that our scheme offers an enhanced ad delivery ratio and reduces the network traffic overhead in ads dissemination via VANETs.
