Feedback Capacity of the Gaussian Interference Channel to within 2 Bits
We characterize the capacity region to within 2 bits/s/Hz and the symmetric capacity to within 1 bit/s/Hz for the two-user Gaussian interference channel (IC) with feedback. We dev...

Anchor selection with anchor location uncertainty in wireless sensor network localization
We investigate in this paper the anchor selection problem with consideration of anchor location uncertainty, which arises naturally from error propagation problem in successive or...

Sift: A MAC Protocol for Event-Driven Wireless Sensor Networks
Nodes in sensor networks often encounter spatially-correlated contention, where multiple nodes in the same neighborhood all sense an event they need to transmit information about....
