Abstract:	近年來，由於無線通訊技術的快速進步、行動通訊設備的普及、週休二日的來臨、商務活動的熱絡，增加了自行開車或乘坐大眾運輸工具如公車、捷運、火車等的機會，許多相對應的行車服務，諸如線上影音及線上遊戲等多媒體串流的服務以及商務應用之需求性已逐漸提高，因此，如何能夠透過無線網路來提供具品質保證之行車服務是目前非常熱門的議題。本子計畫為三年期的整合型計畫，本子計畫將以IEEE 802.16e/j 為基礎，研發並實作車對骨幹網路之媒體存取層與網路層之通訊技術，以實現車內使用者具品質保證之行車服務。在第一年的計畫中，我們將針對IEEE 802.16e/j 之媒體存取層，研究具服務品質保證(QoS Guaranteed)之通訊協定，其研究議題涵蓋具服務品質保證之單點通訊(Unicast)、群播(Multicast)、廣播(Broadcast)以及具地理位置之廣播 (Geocast)等通訊服務，進行具服務品質保證(QoS) 之頻寬分配(Bandwidth Allocation) 及傳送排程(Scheduling) 等技術。不同於第一年擬進行之QoS Guaranteed 通訊協定，在第二年的計畫中，我們將針對交通流量的改變以導致通訊流量的變化，研究媒體存取層及網路層之Traffic-Aware 通訊協定，探討如何依通訊流量進行網路切割、Relay 佈建及重佈建、Power Control 及Adaptive Modulation 等議題，供使用者在通訊流量改變之環境下仍能享有良好的單點通訊(Unicast)、群播(Multicast)、廣播(Broadcast)以及Geocast 等服務品質。在第三年計畫中，我們將開發BS 及RS 的現有資源，包括天線系統與多頻道系統，搭配協同傳輸之通訊技術，以提高整個IEEE 802.16 網路的效能，使寬頻廣域網路之服務效能得以大量提昇。在實作的部份，本子計畫除了將理論研究成果實作於NCTUns 模擬器以驗證其成效外，我們亦以三年的規畫，在實際無線通訊設備上實作一『行車娛樂及資訊服務子系統』，使車內使用者透過IEEE 802.16e/j 之寬頻網路得以享有線上音樂、線上遊戲、線上影音等具服務品質保證之服務以及獲得加油、停車、餐飲等行車生活資訊。 The advanced wireless communication technologies, popularization of mobile devices and dense transportation network increase the importance and emergency of developing vehicular communication technologies for supporting QoS guaranteed vehicular services. This proposal proposes a three-year integrated project, which aims to design a variety of MAC and network layers technologies for Vehicle to Infrastructure (V-to-I) networks based on IEEE 802.16e/j wireless broadband networks. In the first year, we aim to develop MAC layer bandwidth allocation and scheduling mechanisms for supporting QoS guaranteed Unicast, Multicast, Broadcast and Geocast services based on the IEEE 802.16e/j networks. In the second year, we intend to develop the traffic-aware mechanisms in both MAC and network layers to provide better qualities for Unicast, Multicast, Broadcast and Geocast services and tolerate traffic variations. Research issues including network partition, relay deployment and redeployment, power control and adaptive modulation topics will be investigated. In the third year, we attempt to explore the potential bandwidth resources of IEEE 802.16e/j networks by investigating the adaptive antenna systems technologies, the multi-channel mechanisms and the cooperative transmission mechanisms. In addition to the theoretical study, this proposal also plans to implement the developed mechanisms in NCTUns simulator to verify the performance improvements against the existing mechanisms. Moreover, we will implement the “vehicular entertainment & information service” subsystem in real devices based on IEEE 802.16e/j networks to support vehicular users the QoS guaranteed on-line music, on-line game and on-line move services and provide them with gas stations, parking, and restaurant information.
