現今無線感測器網路的主流規範為電子電機工程師協會(Institute of Electrical and Electronics Engineers, IEEE)所發展制定的IEEE 802.15.4標準。無線感測器網路需要長時間的運作,某些物理因素會干擾訊號接收的強度。如:地形、氣候、擺設方式、硬體設計與其他無線訊號干擾等等,進而影響整個無線感測器網路的傳輸品質。本論文規劃一些測試情境,對於採用IEEE 802.15.4標準的無線感測器網路平台來做情境的測試。藉由固定週期時間的傳送與接收封包,取得接收訊號強度指標(Received Signal Strength Indicator, RSSI)、循環冗餘檢查碼(Cyclic Redundancy Check Code, CRC)偵錯與封包遺失率來分析其效能,分析在各種情況下訊號接收品質的變化情形,最後針對蒐集到的結果做適當的結論。根據測試結果,提出改進方法,提供想要以IEEE 802.15.4標準來建置無線感測器網路的使用者一個參考,在何種情境下能如何佈建使接收訊號能達到最高品質。
The main standard nowadays of wireless sensor network is IEEE 802.15.4, which is developed and set up by IEEE. Wireless sensor network (WSN) needs very long term experiment to put outside. Some factors like topography, climate, the way of deployment, the design of hardware, or other noise of wireless signal and so on, might effect the intensity of the received signal. In this paper, we set some conditions for the WSN platforms, which adopt the ZigBee standard for a long-term testing. It transmit packets to get received signal strength indicator (RSSI), cyclic redundancy check (CRC) Code periodically. Additionally, it analyzes the efficiency of the signal by debugging and transmitting the lose rate to received quality in every situation. Finally, make an appropriate conclusion for the gathered results. This paper would also provide a reference to the users who want to build a wireless sensor network follow IEEE 802.15.4, and in which situation and how to build the highest quality to receive signals.
