WSN Location Privacy Scheme Enhancement through Epidemical Information Dissemination

Abstract

Wireless Sensor Networks (WSNs) are commonly used for animal tracking. Over the years, a significant number of studies have been presented for monitoring moving targets through WSN. At the same time, the location / position information of each target should be available only to authorized entities, e.g., Animal Protection Centers, thus, the position should be kept private. The iHIDE is a location privacy mechanism that uses a non-geographical based routing scheme for packet delivery over WSN. In this paper, we elaborate on that scheme by introducing a routing plan construction algorithm. Furthermore, we enhance iHIDE by adopting the use of epidemical data dissemination as an enforcing privacy technique. Finally, we evaluate through simulations the scheme against other commonly used location privacy overlays in terms of network overhead and safety period.
