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.
