本論文中，筆者首先介紹了有關感知網路和其相關技術研究。本研究包含了一個應用於感知網路的可適性排程機制(簡稱ASCN)，在動態頻譜偵測的運作下設計一個新型排程器讓次要使用者能有有效運用頻道裡主要使用者沒有運用的閒置資源，即時傳輸和非即時傳輸均在本論文的考慮範圍內。同時建立了優先權的排序方法，以延遲程度和資源獲取做為依據、用動態調整優先權的方式來降低系統的延遲程度。最後提出緊急佇列的概念，視各個連線的狀況來判斷是否需要進入緊急佇列以避免飢餓狀態的發生並且維持連線傳輸間的公平性。本論文的主要貢獻即是考量次要使用者於感知網路資源缺乏的情況下能夠兼顧傳輸效能外能妥善分配閒置資源並且符合傳輸的公平性、降低平均延遲程度、減少飢餓的情形。

Recent advances in cognitive networks have increased the importance of scheduling. This study sought to enhance the fairness and decrease latency of cognitive networks by introducing and efficient scheduling algorithm capable of starvation and latency without sacrificing lower priority connections. Numerical results demonstrate that compare with others algorithm, it truly improved the starvation and latency problems. It helps real time connection with the lack of resources.
