dc.description.abstract | 感知無線電技術被認為是改善整體頻譜使用效率的一個有效的解決方法,特別是當主要無線電網路有相對較低的頻譜使用率。然而,要實現感知無線電概念,提供主要無線電網路使用者足夠的動機和提供服務提供者額外的收益是非常重要的,如此一來感知無線電行動用戶才有可能偶然地使用主要無線電網路的頻譜,這帶給了頻譜管理一個新的挑戰,在這篇論文裡,我們考慮一個主要無線電網路,它包含一個主要系統基地台和好幾個主要系統行動用戶,因此我們可以建構出一
個感知無線電網路,它包含一個主要無線電網路和好幾個感知無線電行動用戶。我們提出了一個以彼特力競價為架構的頻譜管理策略,使的感知無線電行動用戶可以去競爭主要無線電網路的頻譜,而主要系統用戶可以有折扣去使用頻譜,而且來自感知無線電行動用戶的干擾可以被限制在可以忍受的範圍裡,一旦被感知無線電行動用戶干擾,還可以受到補償來,藉由這些來提供主要系統行動用戶動機,使的感知無線電行動用戶可以使用主要無線電的頻譜。感知無線電行動用戶 一旦被允許可以使用頻譜,他們可以使用一段特定期間而不必做任何的頻譜轉移。因此,除了提供動機給主要系統用戶,整體的頻譜使用率、服務提供者的收益,感知無線電行動用戶可以使用頻譜的機會都可以因此而提升,使的所有相關的團體能達到共贏的局面。 | zh_TW |
dc.description.abstract | Cognitive radio (CR) technology is considered as an effective solution to enhance overall spectrum efficiency, while primary radio network (PRN) typically having
relatively low spectrum utilization. However, to realize CR concept, it is essential to provide enough incentives to PRN and extra profit to the service provider such that cognitive radio mobile stations (CR-MSs) may utilize PRN spectrum bands accordingly, which provides a new challenge for spectrum management. In this paper, we consider a PRN consisting of a primary system base station (PS-BS) and multiple primary system mobile stations (PS-MSs), and we therefore construct a cognitive radio network (CRN) consisting of a PRN with multiple CR-MSs. We propose a spectrum manage policy framework by Vickrey auction such that CR-MSs can compete to utilize the PRN spectrum bands available for opportunistic transmission of CR-MSs. PRN users are granted incentives at a discounting factor to access spectrum bands and being compensated for possible operating interference from CR-MSs, while the interference is constrained under a tolerance level without losing satisfaction for PS-MSs. Once CR-MSs are granted the spectrum bands, they can utilize the spectrum bands for certain duration without any spectrum handoff. Consequently, in addition to incentives to the PRN, the overall spectrum utilization, the profit of the service provider, and the opportunity of accessing spectrum for the CR-MSs are enhanced to achieve co-win situation for every involved party in cognitive radio networks. | en |
