這篇論文提及了一個可運作於藍芽網路下的彈性頻寬分配管理機制，稱之為Bandwidth Based Polling（BBP）。在BBP機制之下，我們首先定義了一個頁框構造，並依此透過Master對Slave的輪詢以分配時槽與每一個有頻寬需求的Slave。由於允許一個Slave在一個Frame中被輪詢多次，因此我們可以在藍芽網路原本封包形態不多的情形下提供彈性的頻寬組合以適應每個Slave的多樣性需求。至於BBP的延伸版本（BBP-ext）則同時提供對SCO Link及某些對頻寬沒有固定需求之Slave的支援。透過模擬的結果，我們發現BBP在頻寬管理下所展現的效率及公平性，同時透過對輪詢次數的控制，我們可以在較高的頻寬分配彈性及較長的頻寬分配協調時間二者中，求取一個適合本身需求的平衡點。

A flexible bandwidth management scheme namely Bandwidth-based Polling (BBP) for Bluetooth is proposed. A framing structure of time is defined in BBP, and the master allocates proper number of slots for each active slave in a frame. BBP allows the master to poll a slave more than once to achieve high flexibility for bandwidth allocation. The calculation of the polling time as well as the payload type for a slave is according to the bandwidth requirement of the slave and the limit of the frame size controlled by the master. Extension of BBP for supporting slaves with the SCO link and slaves without bandwidth requirement (best-effort slaves) is also proposed. Simulation results have shown the efficiency and fairness of BBP in bandwidth management. The flexibility of bandwidth allocation depends on the maximum polling time preset by BBP. A larger maximum polling time makes the higher flexibility of bandwidth allocation at the expense of a longer latency before reaching the equilibrium state.
