在車用網路(VANET)是這幾年熱門的研究領域之一。在車用網路中,連線主要分為車與車之間直接的無線通訊(V2V)、車輛與道路中固定存取點的無線通訊(V2R)和道路中固定存取點與車輛的無線通訊(R2V)。因為車用網路的拓樸具有高移動性,許多既有的無線路由協定並不適用於車用網路。在市區道路中,道路中固定存取點受限於車輛的高速移動無法有效的找尋未知位置的移動車輛。本論文即探討利用分層化的方式擴展道路中固定存取點管理監控的範圍。我們使用NS2模擬其效能,同時與其他常見的無線路由方法比較。結果顯示我們提出的方法,能提供較低的網路延遲時間,和低的overhead。

Vehicular ad-hoc Network (VANET) is one of the most popular research areas in recent years. Connections over vehicle to vehicle (V2V), vehicle to roadside unit (V2R) and roadside unit to vehicle (R2V) are three major common communication types in VANET. Since the highly mobile traffic topology of vehicles, most existing routing protocols for wireless communications are not suitable for VANET .The roadside unit (RSU) is not effective to search the moving vehicles of unknown position on the urban road due to the high relative speed between vehicle and RSU. In this paper, we propose using method of dividing level which can extend RSU’s managing range. The performance of our routing protocol is validated via NS2 simulations. The results show that our routing protocol outperforms other wireless routing protocols in terms of lower delay time and lower overhead.
