無線網路頻譜共享方案之研究

在本論文中，我們研究了分散式動態頻譜協定，使得Ad-Hoc D2D能有機會的使用蜂窩用戶活躍的頻譜。在我們的協定中主要有兩個步驟，首先是對於D2D用戶的功率控制。因為D2D的使用會造成macro用戶的頻寬被限制，是由他們所造成干擾的多少決定，功率控制將是該協定性能的主要決定因素。一旦計算出允許的傳送功率，第二個步驟將一個D2D用戶去尋找到達預期的目的地，無論是單跳或是多跳路徑。最後，在模擬結果充分的說明那些干擾的影響，我們將展示的是，當多跳路徑用於連接一對D2D來源與目的地，可以實現較低平均數目的跳點和節省很大的功率。

The purpose of this thesis is the apply a distributed dynamic spectrum protocol to make the use of Ad-Hoc device-to-device users are able to have the chance to use the spectrum from cellular users. Two main steps requires in our protocol. First step , power control of D2D users. Due to the use of D2D, the macro users’ bandwidth were limited. As for how much D2D generate interference to macro users’, the power control would be crucial. Once an allowance transmit power be calculated out , starts the second step. Second step take D2D user to find the excepted destination from either single-hop route or multi-hop routes. At last, results of those simulation fully explained those interference effect. This project displayed when the multi-hop routes are used to connect D2D pairs among sources and destinations. From the result the average number of the low hops could be achieve and saved large amount of power.
