如何讓大規模動態物聯網中的裝置可以透過網路將資料傳到其它裝置，是物聯網研究上一個很重要的議題。若同時要達到避免廣播風暴、適應動態環境、並具備低耗能等特性，目前還沒有可以實際應用到現實環境中的路由協定。本文介紹的LF-GFG路由協定是第一個可以滿足上述性質的大規模動態物聯網路由協定，可望解決目前困境並加速物聯網實現的腳步。

Routing protocol of the dynamic large-scale internet of things is an important issue. The proposed location-free greedy-face-greedy (LF-GFG) routing protocol is the first delivery-guaranteed location-free routing protocol which can be used in the dynamic large-scale internet of things. We introduce LF-GFG in this paper to help people solving the problem of developing the IoT.
