中文摘要 | 工業,科學和醫用(Industrial, Scientific and Medical;ISM)頻段的開放,對於公眾利益(Public Advantage)、開放式創新(Open Innovation)有極大助益。而電視空白頻段(TV White Space;TVWS)是各國經過數位電視轉換後空出來的頻譜資源,一般認為最有潛力能延續、擴大ISM頻段所帶來的好處。在眾多使用TVWS的方法中,以資料庫搭配多存取點(Access Point;AP)的網路架構最受歡迎。在本篇文章中,針對資料庫搭配多AP的網路架構,我們提出了一個以AP操作區間為基礎的資源分配演算法,使資料庫能充分利用AP回報的資訊,提升頻譜利用率及系統總傳輸量。和其他的資源分配法相比,我們所提出的方法能降低AP分不到資源的機率,特別是資源不足時。 |
英文摘要 | The open of industrial, scientific and medical (ISM) band for public is very helpful to the public advantage and open innovation. TV white space (TVWS) is another spectrum resource beyond digital TV transition, has a potential to continue and expand the advantages brought by ISM band. To exploit TVWS, a database along with multiple access points (APs) is the most popular network structure. In this paper, an AP-operation-region-based resource allocation algorithm is proposed for this type of network. The information feedback from APs is sufficiently employed in the proposed algorithm such that the spectrum utilization efficiency and system throughput can be improved. Compared with other resource allocation algorithms, the proposed method can reduce the probability of non-allocation of APs, especially under insufficient resource. |
