The abstract Data delivery in vehicular ad hoc networks (VANETs) has become one of the most challenging problems due to the rapid movement of vehicles and their bounded communication ranges. How to more efficiently transmit the sensing data about the region of interest to AP is discussed in this paper. Previous work hasn’t distinguished node types to forward data packet commonly, the delivery ratio and delivery latency is highly possible to reach intolerable dimensions. This paper utilizes the prominent characteristic of buses, and proposes a data forwarding scheme（MUQ） based mobile roadside unit (MU) with quality of service (QoS) guarantee for VANET applications that support both periodic and event-based data reporting. The aim of this paper is to minimize expected minimum delay (EMD) of the packet under the premise of guaranteeing QoS. The performance measures of MUQ are evaluated using simulation. The simulation results indicate the efficiency and availability of MUQ scheme presented in this paper.
