摘要: 为降低车辆的整体能耗并减少数据传输时间,提出一种基于无线宽带(WIFI)的公交车载数据传输调度策略。建立公交车载无线传输问题的数学模型,应用遗传算法对其进行求解,得到优化的车辆传输序列。根据该传输序列,结合相应的流程对车辆的传输进行调度。实验结果表明,该调度策略与以先来先服务为基本原则的传统方式相比,能节省16.8%的能耗,减少38%的高优先级数据传输时间。

Abstract: In order to reduce the cost of power and the time of transmission in the public transport vehicle wireless data transmission, this paper proposes a schedule strategy based on Wireless Fidelity(WIFI). The strategy models a solution by applying genetic algorithm to obtain a public transport vehicle sequence which satisfies the schedule process. Simulation results demonstrate that compared with the traditional First Come First Served(FCFS) policy, the proposed schedule strategy performs much better by saving 16.8% power cost and reducing 38% high priority data transmission time.
