雖然GPS提供高精度的定位服務，但是視線傳播效應的影響使得它無法應用於室內的情況。如果能建立無線感測網路，就可利用不同的訊號傳播，如訊號傳送時間(Time of arrival)、訊號接收角度(Angle of arrival)、接收訊號強度(Received signal strength)做為室內定位的應用。本論文利用無線感測網路的接收訊號強度做室內定位。此系統的設計概念是利用無線感測網路中的節點做移動載具的定位。移動載具可從已知的節點位置，透過擷取各節點的訊號強度計算位置。初步的系統硬體及軟體設計已完成並以不同的路徑實驗做測試，文末對系統的表現和缺點做討論。
Although Global Positioning System (GPS) has been verified to offer high accuracy positioning, it is constrained by line of sight signals from satellites that indoor applications are not available. Based on signal propagation, different positioning techniques can be applied using time of arrival (TOA), angle of arrival (AOA) and received signal strength (RSS), if a wireless sensor network can be established.
In this thesis, a wireless sensor network is established for indoor positioning utilizing the received signal strength technology. In the proposed system, a mobile vehicle is used in positioning for guidance through an established RF beacons from the wireless sensor network concept. From known beacon positions, the mobile vehicle can calculate the received signal strength from all beacons to determine its mobile position in real time. The theoretical support to system hardware and software design has accomplished the proposed system in preliminary. Methodology is verified with different scenario tests. The results are discussed with defects and achievements.
