Please help me in developing verification environment for 802.11 ac

Hi All,
I am Sreevani Raichur, Working as a verification engineer.
I am having little experience in system verilog and UVM. But I never handled a verification project alone. Fortunately in my present company I got an opportunity to develop the verification environment alone for 802.11 WI_FI protocol. We don’t have any VIP s to get the expected packets. How can I verify the actual data? . Do I really need to duplicate the entire protocol to generate expected data? or do we have any open sources for it? Please help me out.

Thanks in adavnce.
