本論文的主要目的是以IEEE P802.11ah/D10.0Draft Standard為目標,使用Xilinx Virtex6 FPGA開發板(xc6vlx240t/ff1156/-2),對802.11a/g網路通訊協定的嵌入式收發平台進行修改,加入802.11ah中的Target Wake Time與不同的協商方式,其一為在association procedure加入TWT IE來協商,另外則是在連線成功後傳送Setup Frame攜帶TWT IE來協商,以及Speed Frame Exchange。論文內容主要修改原架構中封包從CPU High到CPU Low的傳送過程,並且在軟體方面增加傳送端和接收端的功能以符合Speed Frame Exchange的規範。而在實體層方面,新增FPGA電路以實現TWT相關功能,並修改signal使得接收端能收到Speed Frame Exchange中所需要的參數,另外還修改了時間間隔和網路配置向量(NAV)的硬體電路,來完成Speed Frame Exchange的溝通。
The main purpose of this thesis is to orientateIEEE P802.11ah/D1 0.0 Draft standard, and modify for the 802.11a/g network communication protocol with Xilinx Virtex6 FPGA board (xc6vlx240t/ff1156 / -2),.We implement the Target Wake Time,different way of negotiating TWT,one of the way is that negotiate TWT in the association procedure with TWT IE,the other one is that transmit setup frame with TWT IE to complete TWT negotiation,,and Speed Frame Exchange.In order to achieve our goal,we modify the packet transfer process from CPU High to CPU Low to change the original architecture processand add the behavior of transmitter and receiver in order to meet the specification of Speed Frame Exchange in terms of software.In terms of hardware we add hardware circuit to implement the features of TWT,and modify the signal,let receiver can receive the parameters which Speed Frame Exchange required,and also we modify the hardware circuit of time interval and NAV to achieve the Speed Frame Exchange.
