Abstract

The paper proposes novel dynamic distribution-aware data dissemination (DDA) based Publish/Subscribe system for Vehicular Ad Hoc Networks (VANETs). Based on the characteristics of vehicles´ moving in VANET, a notification-token mechanism is proposed: only the notification-tokens´ holder (notification-brokers) can broadcast information to subscribers nearby-based on the calculated delivery probability with interested subscribers and predicted dynamic distribution of those subscribers in this area, it can dynamically adjust notification-tokens in the VANET. Then the notification-brokers can broadcast the received notification to other subscribers accordingly. By dynamically adjusting notification-tokens, this solution can efficiently control notification-broker´s distribution and guarantee data dissemination. Simulation results based on a real city map and realistic traffic situations show that the DDA based Publish/Subscribe system performs much better in terms of delivery efficiency and delivery delay over other solutions.
