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
