Abstract-Wireless sensor networks (WSNs) consist of many sensors working as hosts. These sensors can sense a phenomenon and represent it in a form of data. There are many applications for WSNs such as object tracking and monitoring where the objects need protection. Providing an efficient location privacy solution would be challenging to achieve due to the exposed nature of the WSN. The communication protocol needs to provide location privacy measured by anonymity, observability, capture-likelihood and safety period. We extend this work to allow for countermeasures against semi-global and global adversaries. We present a network model that is protected against a sophisticated passive and active attacks using local, semi-global, and global adversaries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
