Toward dependable networking: secure location and privacy at the link layer

WLAN and other radio broadcast technologies are now commonplace. However, the widespread usage of these technologies comes at the price of loss of location privacy. Although a number of network-level solutions exist to lessen the problem, we describe an improved approach to location privacy at the link layer. We present a generic mechanism and then map it to the common IEEE 802.11 protocol set. The article finally provides an analysis of our mechanism in terms of privacy and performance.
