In this demonstration we present the Brown Dwarf, a distributed system designed to efficiently store, query and update multidimensional data. Deployed on any number of commodity ...
Sensor networks have recently gained popularity for a wide spectrum of applications. When performing monitoring tasks in hostile environments, security requirements become critical...
— In location-based, mobile continual query (CQ) systems, two key measures of quality of service (QoS) are: freshness and accuracy. To achieve freshness, the CQ server must perfo...
Freshness and accuracy are two key measures of quality of service (QoS) in location-based, mobile continual queries (CQs). However, it is often difficult to provide both fresh and ...
This paper addresses design exploration for protocols that are employed in systems with availability-consistency tradeoffs. Distributed data is modelled as states of objects repl...
