Wireless sensor networks (WSN) have received a lot of attention recently due to their wide applications such as target tracking, environment monitoring, and scientific exploration in dangerous environments. Secure time synchronization is a key service for wireless sensor networks (WSN). Time synchronization protocol synchronizes local clocks of group nodes to a common clock. In group, some of the...
Several studies suggest link between repolarization alternans and arrhythmia. A potential target for minimization of alternans amplitude is pharmacological flattening of restitution function, which links a diastolic interval (DI) and subsequent action potential duration (APD). While our recent studies have shown that DI dependent restitution is not a necessary mechanism for alternans, in circumstances...
Wireless sensor networks suffer from the problems of congestion, which lead to packet loss and excessive energy consumption. In this paper, we address both node-level and link-level congestion and propose a new routing protocol namely ant based routing with congestion control (ARCC), for wireless sensor networks, which takes into account the congestion of the network at a given instance and proposes...
In recent years, the exponential growth of Internet users with increased bandwidth requirements has led to the emergence of the next generation of IP routers. Distributed architecture is one of the promising trends providing petabit routers with a large switching capacity and high-speed interfaces. Distributed routers are designed with an optical switch fabric interconnecting line and control cards...
GridXl is a computational grid designed and built to link resources at a number of research institutions across Canada. Building upon the experience of designing, deploying and operating the first generation of GridXl, we have designed a second-generation, Web-services-based, computational grid. The second generation of GridXl leverages the Web services resource framework, implemented by the Globus...
