中文摘要 | 廣播技術經常被使用在無線資訊系統來進行資料散佈 (data dissemination)。然而,由於行動裝置受制於電池電力,加上無線通訊的昂貴費用,對行動通訊使用者(mobile user-MU)而言,無法一直連線抓取資料。此外,MU 本身具移動性(mobility),不會在一個基地台( base station)的服務範圍待太久,當MU 離開基地台的服務範圍,就無法存取該基地台所提供的查詢資料。因此一個好的無線廣播資訊系統須能主動告知MU適當的存取行為(access behavior),使得 MU 能夠將有限的電力作最好的利用,儘快蒐集足夠滿足查詢需求的資訊,快速回應給MU。本篇論文提出一個完整的機制,使行動通訊使用者在行動環境中有效率的存取廣播的資料,希望能發展一種利益導向(benefit-oriented)的資料擷取協定,讓行動通訊使用者能夠快速抓取所需的資料。 |
英文摘要 | Broadcast technology has become a popular method for data dissemination in wireless information systems. However, the higher wireless communication cost and power of mobile device is limited. It is not suitable for mobile user continuous listening to public channel access data. In addition the mobility of the mobile user, cause the mobile user will not stay at a base station too long. When mobile user leaves from the original base station such that he can not access data from base station Therefore a broadcast strategy needs to actively tell the mobile user (MU) a suitable access mode for retrieving the broadcast data. In this paper, we propose a more complete mechanism for mobile clients to efficiently and effectively access broadcast information. Our goal is to develop a benefit-oriented retrieval protocol so that a mobile user can retrieve more valuable broadcast information by consuming less power of a mobile device. |
