臺灣博碩士論文加值系統

　　近年來無線網路的快速發展，使得行動隨意網路(Mobile Ad-hoc Network, MANET)的技術趨於成熟。而車載隨意網路(Vehicular Ad-hoc Network, VANET)便是MANET的延伸應用之一，主要能夠使行車環境更加安全與便利。車載隨意網路需要一個大型的模擬場景來測試研究人員的研發結果，模擬場景內許多節點以雜亂的方式移動，並且透過網路連結相互作用，而為了測試與排除故障，節點與其之間的網路交互作用必須要透過檢查來確認錯誤，而這個過程可以透過互動式的圖形介面來顯示各種不同的細節。
　　在本研究中，我們提出一種視覺化模擬框架，透過模擬器的輸出結果，轉換為清楚可見的圖形化模擬動畫，並且使用者能夠從各種需要的角度來檢視整個模擬環境的情況，達到方便檢查與除錯的需求。

　　In recent years, the rapid development of wireless networks makes the technology of Mobile Ad-hoc Network (MANET) more mature. Vehicular Ad-hoc Network (VANET) is an extend application of MANET, and VANET aims to make the driving environment more safety and convenient. The research of VANET needs a large scenario to simulate the result that proposed by the researchers. In the simulation scenario, nodes move in a complicate way and link to other nodes via the wireless network. We can display this simulation in a visualized platform to show the details when a VANET simulation is running.
　　In this study, we propose a visualization framework for VANET simulator, and display animation of the simulation result generated by the simulator. The proposed visualization framework can let user view the entire scenario in different ways for personalization purpose.
