Hybrid vehicular ad hoc networks (VANETs) allow Inter-Vehicle Communications (IVC) and Roadside-to-Vehicle Communications (RVC), exploiting this property a new protocol is proposed in this thesis. The proposed protocol utilizes the Roadside Units (RSUs) for the implementation of a registration process which allows for the provision of a localization service. The presented RSUs architecture breaks the VANETs into smaller regions managed by a RSU in which individual On Board Units (OBUs) register providing its current position and velocity vectors. Using the data provided by the OBUs, a localization service can be implemented, thus facilitating locating the destination vehicles. When source nodes need to send data, the location of the destination is calculated at the source RSU and the destination RSU using controlled flooding locates the destination vehicle and establishes a route path between source and destination. Simulation results under the NCTUns Network Simulator and Emulator environment of the proposed protocol show that it performs well providing good throughput, high packet delivery ration, low delivery delays with very low overhead.
混合式車載隨意網路(VANETs ) 是存在車輛間會有內部的通訊(IVC)及路邊裝置與車輛間的通訊的(RVC),而在此篇論文便利用這些特性提出了一個新的協定。所提出的協定利用了路邊裝置(RSUs) 來實行註冊的程序及允許定位的服務。在此提出有路邊裝置(RSU)的架構是允許將VANETs分解為許多容易處理的區域,此區域使得車內的感應器裝置(OBUs)可以與RSU註冊來獲得其目前的位置及速度向量資訊。利用這些OBUS提供的資料,一個定位服務就可被實行,因為那些資料可容易找出目的端車輛的位置,當來源端的點需要傳送資料,目的端的位置可以藉由RSUs及 藉著控制在RSUs範圍中的flooding來定位,而藉此就可提供一條由來源端到達目的端路由路徑。模擬的結果是在NCTUns Network Simulator及所提出的協定的模擬環境所作的,結果表現能在很小的額外負擔下,得到了很好的網路流量,很高的封包傳輸率,和很低的延遲時間。
