Efficient route guidance in vehicular wireless networks

With the rapid proliferation of Wi-Fi technologies in recent years, it has become possible to utilize the vehicular wireless network to assist the route guidance for drivers in a cooperative approach, aiming to mitigating heavy traffic congestion. In this paper, we investigate into the route guidance problem in vehicular wireless network, and then propose two efficient routing algorithms, i.e., centralized route guidance and distributed route guidance, according to different situations. A hybrid framework is then proposed to provide optimized routing decisions in a uniform way. Simulation results in Simulation of Urban MObility (SUMO) indicate that, our route guidance schemes achieve much better performance than traditional GPS-based navigation and randomized routing.
