智慧型運輸系統為近年來非常熱門之應用，智慧型車輛的車載資通訊系統是透過車載隨意網路與其它車輛的車載資通訊系統以及道路旁的路側裝置來進行資料傳遞，藉此增進行車的安全性以及運輸效率。除此之外，還能夠提供許多便利的服務給乘客與駕駛。然而車載隨意網路是透過無線技術來傳遞訊息，因此容易遭受到惡意者的攻擊，使得智慧型車輛中的車載資通訊系統無法正常運作，甚至引起車禍的發生。因此建構一個高可靠度且具備容錯能力的車載隨意網路是非常重要的。在本計畫中，我們將探討以下 4項議題於車載隨意網路之中： (1)車間通訊容錯協議演算法；(2)車路通訊容錯協議演算法; (3)車間通訊與車路通訊之即時容錯協議演算法；(4)車載隨意網路之故障裝置隔離機制。在時程方面，本計畫預計以三年的時間來解決上述之問題。 Intelligence Transportation System (ITS) is one of the popular applications in recent years. Intelligent vehicles use Vehicular Ad Hoc Networks (VANET) to communicate with other intelligent vehicles and Road-Side Units (RSU). With VANET, intelligent vehicles can increase transportation safety and efficiency and also offer numerous convenient services to both passengers and the driver. However, messages are transmitted wirelessly in VANET and therefore vulnerable to malicious attacks. In the event of a malicious attack, the On-Board Unit (OBU) in intelligent vehicles will not function properly, and accidents are likely to occur. Therefore, building a highly reliable and fault-tolerant VANET is of high important. In this project, we attempt to visit the following four issues in VANETs: (1) fault-tolerant problems with Vehicle-to-Vehicle (V2V) communication in VANETs; (2) fault-tolerant problems with Vehicle-to-Roadside (V2R) communication in VANETs; (3) early stopping agreement problem with V2V communication and early stopping agreement problem with V2R communication in VANETs; (4) the isolation mechanism of faulty unit in VANETs. This project is expected to take three years to complete the above four issues.
