隨著無線網路技術的成熟，車載資通訊正成為一個新興的網路服務與應用。本論文將透過集中式車輛同儕網路系統之車載資通訊服務探索平台提供有效與合理的服務探索。本文的議題著重於制定一項車載資通訊服務探索平台適用於車輛的網絡環境。當用戶行駛在道路上並需要服務時，有兩個問題需要考慮：（1）如何搜索服務提供者以產生候選人名單（2）如何從候選人名單中選擇合適的服務提供者。本論文建立服務探索平台的主要機制包含車輛同儕網路通訊協定與些播(somecast)協定以解決上述的問題。車輛同儕網路通訊協定提供車載資通訊服務探索所需的溝通機制，中央服務器、用戶端和服務供應商使用車載資通訊服務標記語言（TSML）進行信息通信。服務探索平台使用些播(somecast)協定為三階段架構，分別為服務供應商搜索階段、服務供應商選擇階段、服務供應商訂購階段以實現高精準度的服務探索。本論文的實驗結果展示集中式車輛點對點車載資通訊服務探索平台的性能優點。

With the maturation of wireless networks technologies, Telematics service is becoming a new rising and popular network service and application. In this thesis, a centralized vehicular Peer-to-Peer Telematics (C-VP2P) service discovery platform is proposed to provide efficient and feasible service discovery. This thesis focuses on the issues of developing a Telematics service platform over the vehicular network environment. When a user needs a service on the road, two issues need to be considered: (1) how to have the candidate list of service providers? (2) how to select suitable service providers from the candidate list? The main functions of the proposed service discovery system include the vehicular P2P messaging protocol and the somecast protocol. The vehicular P2P messaging protocol provides the communication mechanism for Telematics service discovery among Telematics central server, clients and service providers using our proposed Telematics Service Markup Language (TSML). The proposed service discovery protocol using the somecast protocol embraces service provider search phase, service provider selection phase and service provider subscription phase to achieve high precision service discovery. We also exhibit the performance merits of the proposed C-VP2P Telematics service discovery platform in this thesis.
