藍芽技術與感測器節點

Bluetooth and Sensor Node

摘要


本文介紹無線感測器網路(WSN)中,一個感測器節點的硬體所需要的規格。針對無線通訊部分,討論以藍芽(bluetooth)做其無線傳輸介面的優缺點,認為藍芽無線模組對WSN的模擬有其便利性,但從省電的觀點看來,仍大有改進空間。藍芽技術結合其他更省電卻較簡單的RF,用於WSN的模擬,則是一可行的辦法。

並列摘要


This article addresses the necessary specification of a hardware platform for sensor node in wireless ad hoc sensor network. After that,it discusses about the advantage when Bluetooth radio is used and the trouble we can meet in implementation. For network algorithm development, Bluetooth module gives us many help to ease the work, but the power consumption in standby is still too great. For that a dual radio approach combines bluetooth with a ultra low power radio technology is proposed.
