Multiuser Diversity with Imperfect Channel Quality Feedback in MIMO Broadcast Networks
—In this paper, we analyze the impact of imperfect channel quality feedback on the scheduling algorithms that exploit multi-user diversity. We consider a time-slotted MIMO broadc...

Surviving sensor network software faults
We describe Neutron, a version of the TinyOS operating system that efficiently recovers from memory safety bugs. Where existing schemes reboot an entire node on an error, Neutron...
