Short paper: Random IDs for preserving location privacy

The privacy aspect is often neglected in many electronic systems. With the emergence of ubiquitous systems, privacy will become an even more important aspect than it has been in the past. Location privacy - the information where exactly a node is currently located - is one aspect. This paper classifies several kinds of attacks on location privacy. It examines the results of these attacks on a scheme utilising changing identities to preserve the users’ identities. Simulation results show the influence of the number of nodes and the backoff time between transmissions on the nodes’ location privacy.
