5.1 總結
本論文的目的,在於提出一個新式定位機制,以修正原本利用 RFID 設備做 定位的 LANDMARC 方法中,因為指引點不明所造成定位上的議題。
實驗結果顯示,本論文所提出的新式定位機制,在定位的平均效能上,比原 本使用 LANDMARC 方法來的優秀,同時也有確切的指引點數目顯示,因此,整體 的定位效能有顯著的進步,相對的有效定位涵蓋範圍也跟著提高。
因此,當環境底下 RFID 讀取器不夠時,因為成本考量,改採用大量且成本 較低廉的指引標籤以延伸可定位的有效範圍,本論文希望這個折衷的作法在實務 發展上會有更大的應用優勢。
5.2 未來發展
近幾年來快速興起的 RFID 射頻辨識技術,大多都把重點放在硬體設計的研 發上,包括小型化標籤的尺寸、控制天線的收訊範圍以及標籤的可重用設計等 等,而軟體的部分像是演算邏輯的改進也在最近漸漸受到重視,RFID 的應用相 信不論是在硬體或軟體上,都需要有相輔相成的發展才能有更廣泛且全面的未 來。
本論文藉由二階段分群法引入的探討,將焦點放在定位效能的軟體面改善 上,在未來,有關於本論文內其他可行主題的探討,例如:其他啟發式方法的運 用、更精確的定位數值分析、RFID 設備發射訊號強度處理模型,以及將更多環 境條件納入、複雜度更高的多變量分析,參考價值第二高的分群數據引入與否,
都是此類型室內定位應用中,值得再深入的研究主題。
