Abstract

Being composed of car electronics and road-side communication devices, vehicular ad hoc networking (VANET) is the heart of intelligent transportation system. Beside car-to-car communications, the system also communicates to centralized points in infrastructure networks. Given that data load is heavy when the density of cars is high and that they move fast, roadside electronics potentially face congestion. This study designs a novel framework finding the best route with respect to efficiency and fairness among road-side units. The introduced algorithm exploits both position data and load to make routing decisions optimally. Simulation results clearly demonstrate the soundness of our proposals.

车辆自组织网络中路边单元的位置感知和负载平衡数据传输
车载自组织网络(VANET)是智能交通系统的核心,由车载电子设备和道路侧通信设备组成。除了车对车通信,该系统还与基础设施网络中的中心点通信。考虑到当汽车密度高且行驶速度快时,数据负载会很大,路边的电子设备可能会面临拥堵。本研究设计了一个新的框架,在考虑效率和公平性的前提下,寻找最优路径。该算法同时利用位置数据和负载进行最优路由决策。仿真结果清楚地证明了我们的建议的合理性。
