利用WAVE/DSRC應用動態導航於車用行動通訊網路之研究

The Study of Dynamic Navigation with WAVE/DSRC in VANETs

摘要


於本文中,我們提出了一個利用IEEE標準中新的車用協定通訊技術(Wireless Access in Vehicular Environments; WAVE)/專用短程通訊(Dedicated Short Range Communications; DSRC)於車用行動通訊網路(Vehicular Ad Hoc Network; VANET)的動態導航應用之研究架構。當動態導航引擎接收到來自車用行動通訊網路的資訊後,將會做重新的路徑規劃。在此研究中,其中採用迴路偵測的方法,來檢測當進行即時封包轉發時,其重複廣播發送的封包。最後,測試結果顯示動態導航應用於高移動性的情況下,其傳遞即時的訊息是有效率的。

The integrated architecture for the implementation of dynamic routing/navigation application in Vehicular Ad Hoc Network (VANET) environment using Wireless Access in Vehicular Environments (WAVE)/Dedicated Short Range Communications (DSRC) is proposed. Dynamic navigation re-routes after receiving traffic event from VANET is examined in the test using a WAVE On-board-Unit (OBU) and a WAVE Road-Side-Unit (RSU) as the network node. In this study, the loopback detection method is adopted to detect re-broadcasting packets when a forward request in real-time needed. Tests showed that the real-time traffic messages are delivered efficiently for dynamic navigation application with high mobility situations in the end.
