摘要: 近年來隨著無線網路快速發展,人們可以無所不在地使用網路,車用行動通訊網路是無線移動網路中一種快速發展的新型態,它是由汽車的移動所構成的網路模式,近來有不少針對車用行動通訊網路效能分析的研究,其中,大部分的研究都是在探討通訊協定、傳送效率或是傳輸延遲,他們大部分的結果都是利用網路模擬或是統計資料來取得。在車用行動通訊網路中,連線時間會影響到資料傳輸與繞徑演算法的表現,所以有必要建立更精確的數學模型來正確預估其連線生命週期,進而改善效能。所以在這篇論文中,我們提出一個數學分析模型來計算出車用行動通訊網路在都會區中的期望連線時間,另外,我們考慮在每個十字路口加上紅綠燈後,所造成連線時間的變化,我們一樣提出數學分析模型來分析其期望連線時間。最後,我們將提出模擬結果來驗證期望連線時間數學模型的正確性。
Since the recent rapid development of wireless mobile networks, people can access the network ubiquitously. Vehicular ad-hoc networks (VANETs) are an emerging new type of wireless mobile ad-hoc networks (MANETs). It’s a mobile network composed of moving vehicles. There are many researches in performance for VANETs. Among those, most researches focus on the communication protocol, delivery ratio, or transmission delay. They are mostly obtained by network simulation or statistical data. In VANETs, communication time will affect data transportation and the performance of the routing algorithm. It’s necessary to build a more accurate mathematical model to estimate the communication time. In this thesis, we present a mathematical analysis model to calculate the expected communication time (ECT) of VANETs in urban city. Furthermore, we consider adding a traffic light to each intersection to observe the influence to the ECT. Finally, we present simulation results to validate our mathematical model in ECT.
