近年來 RFID 在通訊排程方面提出了許多不同的演算法,而其中共同的問題在避免RFID訊號碰撞衝突與相互干擾。本篇論文根據質數特性的通訊排程機制 (Prime based First Come Higher Priority,FCHP),提出一個高效率且容易時作的排程技術。目的在解決終端機隱匿所造成RFID讀取機之間的訊號碰撞問題。FCHP最主要的概念是在於協調讀取機之間同時讀取標籤(Tag)資訊的簡單機制。FCHP透過免競爭排程的方法明顯的改進與預防讀取機間的訊號碰撞問題。另一方面 FCHP 的優點能完全適用在固定與移動式RFID讀取機的使用環境。為了分析 FCHP 對碰撞問題的效能,我們除了將其實作外,也實作了 Colorwave與 Pulse演算法來做比較。實驗中證實了本篇論文提出的演算法在固定與移動式的 RFID 讀取機環境裡可提供優越的系統處理能力與效率。
The problem of scheduling transmissions of dynamic Radio Frequency Identification (RFID) systems has been recently studied. One of the common problems, reader collision avoidance has instigated researchers to propose different heuristic algorithms. In this thesis, we present a prime based First Come Higher Priority (FCHP) transmission scheduling method for reader collision problems that caused by hidden terminal. FCHP is a simple mechanism for coordinating simultaneous transmissions among multiple readers. A significant improvement of this approach is that FCHP prevents reader collisions by giving contention free scheduling. The second advantage of the proposed technique is that FCHP is adaptive in both static and dynamic RFID environments. To evaluate the performance of the proposed technique, we have implemented FCHP along with two other techniques. The simulation results show that the proposed technique provides superior performance in both static and dynamic instances. The FCHP is shown to be effective in terms of system throughput, system efficiency and easy to implement.
