在下一代的無線網路中,由於頻寬的增加、技術的進步,除了以往的資料傳輸之外,同時也能提供多媒體資料的傳輸。所以一個無線網路是否能提供給這些多媒體連線適當的QoS,變成了一個重要的議題。在提出的方法中,我們假設cell中使用的是多方向性的天線,而非傳統無方向性的天線,利用這個特性,我們便能更有效率的預測所須在相鄰cell中預留資源的數量;除此之外,在通道配制上,我們採用頻寬借用的方式作為接受連線與否的方法;結合二者能提供多媒體連線適當的QoS,且能降低call blocking probability (CBP) 、call dropping probability (CDP),並能提高整體頻寬的使用率。
Because of the advancement of wireless networks, it is important to provide quality-of-service (QoS) guarantees as they are expected to support multimedia applications. In this paper we propose a new bandwidth reservation scheme based on the characteristic of the cell equipped with sector antenna. According to this information, the proposed scheme can predict the next location of each connection and precisely reserve bandwidth in appropriate neighboring cells, not all of its neighboring cells. Besides, the proposed scheme uses bandwidth borrowing mechanism to be our call admission control strategy. The combination of bandwidth reservation and bandwidth borrowing provides network users with QoS in terms of guaranteed bandwidth, call blocking and call dropping probabilities.
