Where can I find Peer Reviewed Articles?

Hey guys,

I am taking a class in Computer Mediated Communications.
I have to do some research (10 sources) for a paper.

Can you help me find peer-reviewed/scholarly journals out there on the Web that could possibly give me a theoretical angle on wi-fi in the corporate world?

I know I want my research paper to focus on wireless technology in the commercial sector, like how wi-fi helps/hinders Starbucks business or Schlotscky's business, or any other articles out there that deal with wireless technology strategies in corporations.

I know wi-fi is a very new technology and there may not be much research done on it yet, but any help would be much appreciated.

Thanks
WifiTaco
