We study the problem of aggregating data from a sparse set of nodes in a wireless sensor network. This is a common situation when a sensor network is deployed to detect relatively...

Distributed systems require strategies to detect and recover from failures. Many protocols for distributed systems employ a strategy based on leases, which grant a leaseholder acc...
An explicit slice-based mode type selection scheme for use in H.264/AVC has recently been developed, which preserves the coding efficiency of H.264/AVC without requiring any modif...
This paper presents the design and evaluation of SafeGuard, an intra-domain routing system that can safely forward packets to their destinations even when routes are changing. Saf...
We propose a periodic diagnostic algorithm based on the testing model of computation for real-time systems. The diagnostic task runs on every processor of the system. When the task...
