| Outline of Final Research Achievements |
Many researches addressed data dissemination utilizing inter-vehicle communication. However, there are still some technical challenges in reduced throughput by packet collision and difficulty of communication between cars heading towards opposite directions.
In this project, we propose a wireless multi-channel data delivery method for vehicular ad-hoc networks. The proposed method divides the roads into smaller areas (cells) and assigns one out of four channels to each cell to avoid interference between neighboring cells. Each car communicates with the channel assigned to the cell it is currently running on, and the whole network can use multiple channels at a time. In this way, continuous transfer of data and delivery of large data can be achieved.
