Distributed systems have evolved from highly regular systems to irregular systems that are not based on any specific architecture. Highly optimized distributed algorithms that are often variants of classic data structures have been developed for these systems. However, such approaches may not be effective for applications built on loosely coupled irregular(More)
Our design involves a new and more efficient session-based access validation mechanism. In addition, we evaluate the expressiveness of Geopriv rules for describing a variety of privacy rules. We find a number of limitations and propose some methods for extending the rule notation for addressing these limitations. We conclude with an overview of our(More)
