全球感測網之發展現況與未來議題探討

A Discussion on the Current Development and Future Direction of the World-Wide Sensor Web

隨著感測器及通訊技術的發展，感測器的使用逐漸普及。不論是政府機關、研究團隊皆可部署感測器網路（sensornetwork）以達成各自的目的。但不同的感測器網路常使用不同的資料傳輸及分享協定，造成各個感測器網路成為封閉的系統。全球感測網（World-WideSensorWeb）即是針對此項問題進行探討並提出解決方法。透過開放式標準的制定，不同感測器及感測資料可匯集整合在同一個概念及邏輯架構內。經由連結世界上所有的感測資源，全球感測網預期將可持續不斷地監控世界各地發生的各種環境現象。但全球感測網願景的實現需要各界的投入與配合。因此，本文的主要目的為推廣全球感測網，進而吸引更多研究能量及參與意願一同實現全球感測網的願景。基於本文作者於全球感測網實作及標準開發參與的經驗，此篇文章介紹了全球感測網的概念、發展歷史、不同類型的架構、以及未來潛在的研究方向與議題。 With the advance of sensor and communication technologies, sensor networks have become technologically and economically feasible for organizations and individual scientists to monitor various phenomena. But different sensor networks may define or follow different proprietary data formats or communication protocols, which results in sensor network silos and information cannot be exchanged between silos. One of the main objectives of the World-Wide Sensor Web is to address this interoperability issue with open standards. In this case, all the sensors and sensor data in the world can be integrated into the same conceptual and logical framework, with which the sensor web can continuously monitor various events happen everywhere. In order to realize the sensor web vision, we need collaborations across many organizations and individuals. Therefore, the main purpose of this paper is to further promote and introduce the sensor web in order to attract more research and collaboration energy into the realization of the sensor web vision. Based on the author’s multi-year experience developing and defining sensor web applications and standards, this paper introduces the sensor web concept, history, different types of architectures, and some potential research directions and issues.
