摘要:

近几年来,车联网领域快速发展并引起广泛关注。在此背景下提出了一种混合Wi-Fi、WiMAX 和3G/LTE的网络架构,在这种架构下,车辆可以根据自身的情况选择合适的方式接入网络。网络带宽分享采用基于联盟合作博弈的方式,车辆可以选择加入或离开合作联盟来最大化自身收益。模型从理论上证明了通过车辆间的效用分配与博弈合作,最终将形成一个纳什稳定的联盟划分并能适应车辆的动态变化。仿真结果表明,模型的算法性能接近于最优联盟分配。

Abstract:

There has been significant interest and development in vehicular Ad Hoc network(VANET)during the last several years. An aggregated networking architecture using Wi-Fi,WiMAX and 3G/LTE technologies was proposed. In this architecture,a proper way was chosen by vehicles to achieve 1ow-cost network access. This model used a coalition formation game for bandwidth sharing among vehicles,where each can take an individual decision to join or leave a coalition,depending on its utility. It was showed that the vehicles could self-organize into a Nash-stable partition and adapt this partition to environmental changes. Simulation results show that,this approach works efficiently in bandwidth sharing in VANET compared to optimal partition.

Key words: VANET, coalition formation game, aggregated networking architecture, bandwidth sharing
