智慧型傳輸系統(Intelligent Transportation System)是目前 世界各國都在提倡的基礎建設,其主要是將資訊以及通訊技術結合進 一般的交通運輸設施和車輛當中。雖然智慧型傳輸系統含括的領域很 廣,但是我們認為通訊系統是其中一個相當重要的角色,它為眾多車 輛、路旁設施以及管理系統之間建立了溝通的管道。 在此篇論文當中,我們提出了一個新的通訊網路架構,稱作異質 性車輛網路(Heterogeneous Vehicular Network),並針對此架構設 計了一個移動模式已知路由協定。異質性車輛網路結合了IEEE 802.16e 無線都會網路以及IEEE 802.11p 車輛隨建即連網路技術, 並分別保留其較廣的涵蓋範圍以及較高資料傳輸率的優點。車輛在異 質性車輛網路中彼此之間能進行通訊並且可隨時隨地連上網路。 我們主要著重在異質性車輛網路上的路由協定設計,此路由協定 不同於一般使用在隨建即連網路或是車輛隨建即連網路的路由協 定。在異質性車輛網路中,有了無線都會網路基地台的輔助,移動模 式已知路由協定將能在車輛之間建立一條較穩定的路由路徑並且在 網路拓樸變化快速的車輛網路中提供一個較穩定的資料傳輸。 The Intelligent Transportation System (ITS) is a worldwide initiative that combine both information and communication technology to transport infrastructure and vehicles. The field of ITS is very extensive, but we think that communication architecture is the most important role which connect numerous vehicles with roadside infrastructure and management center in the ITS program. In this paper we propose a new architecture, Heterogeneous Vehicular Network (HVN) and a mobility pattern aware routing for HVN. HVN integrates IEEE 802.16e Wireless Metropolitan Area Network (WMAN) with IEEE 802.11p Vehicular Ad hoc Network (VANET) technology and reserves advantages of better coverage in WMAN and high data rate in VANET. Vehicles in HVN can communicate with each other and access Internet ubiquitously. We mainly focus on the routing issue for HVN, because the routing protocol for HVN is different from those used in WMAN or VANET. With the WMAN infrastructure support in HVN, the mobility pattern aware routing protocol can establish a better route path and provide reliable data communication in high dynamic vehicular network.
