Delay Analysis for Multi-Hop Wireless Networks
Abstract—We analyze the delay performance of a multihop wireless network with a fixed route between each sourcedestination pair. There are arbitrary interference constraints on ...

When Feedback Doubles the Prelog in AWGN Networks
We demonstrate that the sum-rate capacity of a memoryless Gaussian network at high signal-to-signal ratio (SNR) can be asymptotically doubled when feedback is available. To demonst...

Capacity- and Bayesian-Based Cognitive Sensing with Location Side Information
— We investigate spectrum sensing by energy detection based on two different objective functions: a Bayesian sensing cost or the network weighted sum capacity. The Bayesian cost ...
