ABSTRACT
Wireless technologies have redefi ned the contours of our world, a world without wires where information is available from anywhere at any time. The huge expansion of wireless technologies, and specifi cally 802.11 wireless data networks, in the last few years has provided a new battle fi eld for information access. End users and corporations are heavily interested in taking advantage of the fl exibility, mobility and freedom offered by wireless technologies to access and share information. The human dependency on those technologies has increased to the point where one can fi nd wireless devices almost everywhere, from network devices to laptops, cameras, and so on. These allow connecting to data networks, like the Internet.
