發布日期:2023-05-17 點擊率:95

網關,作為一個新的名詞,在未來的物聯網時代將會扮演非常重要的角色,它將成為連接感知網絡與傳統通信網絡的紐帶。作為網關設備,物聯網網關可以實現感知網絡與通信網絡,以及不同類型感知網絡之間的協議轉換.既可以實現廣域互聯.也可以實現局域互聯。此外物聯網網關還需要具備設備管理功能,運營商通過物聯網網關設備可以管理底層的各感知節點,了解各節點的相關信息,并實現遠程控制。圖l示意性地給出了以物聯網網關構建的物聯網典型拓撲。用于近程通信的技術標準很多,僅常見的WSNs技術就包括Lonworks、ZigBee、 6LowPAN、RUBEE等。各類技術主要針對某一應用展開,之間缺乏兼容性和體系規劃。國內、外已經在展開針對物聯網網關進行標準化工作,如3GPP、傳感器工作組,實現各種通信技術標準的互聯互通
