Efficient and Effective Techniques for Source and Sink Location Privacy in WSN.
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 10
Abstract
While many protocols for sensor network security provide confidentiality for the content of messages contextual information usually remains exposes. Such information can be critical to the mission of the sensor network such as the location of a target object in a monitoring application and it is often Important to protect this information as well as message content. There has been several recent studies on providing location privacy in sensor networks. We first argues that a strong adversary model the global eavesdropper is often realistic in practice and can defeat existing techniques. We formalize the location privacy issues under this strong adversary model and show how much communication overhead is needed for achieving a given level of privacy. We also proposes two techniques that prevent the leakage of location information: periodic collection and source simulation. In periodic collection provides a high levels of location privacy while source simulation provides trade-offs between privacy communication cost and latency.
