Modelling multi-path problems
—In this paper we consider the behaviour of both primal and dual multi-path algorithms for a simple network of three resources. We examine the equilibrium behaviour of our models...

Equilibria and price of anarchy in parallel relay networks with node pricing
Abstract—We study pricing games in single-layer relay networks where the source routes traffic selfishly according to the strategic bids made by relays. Each relay’s bid incl...

Optimization via communication networks
— It has been known since the early 1990s that backpressure-type algorithms for communication networks (such as the Max-Weight algorithm) can be used to approximately solve stati...

Dynamic data compression for wireless transmission over a fading channel
—We consider a wireless node that randomly receives data from different sensor units. The arriving data must be compressed, stored, and transmitted over a wireless link, where bo...

Unsupervised distributional anomaly detection for a self-diagnostic speech activity detector
— One feature that classification algorithms typically lack is the ability to know what they do not know. With this knowledge an algorithm would be able to operate in any domain...

Overlay protection against link failures using network coding
Abstract—This paper introduces a network coding-based protection scheme against single and multiple link failures. The proposed strategy makes sure that in a connection, each nod...

Rate adaptation via link-layer feedback for goodput maximization over a time-varying channel
Abstract—We consider adapting the transmission rate to maximize the goodput, i.e., the amount of data transmitted without error, over a continuous Markov flat-fading wireless ch...

The Dantzig selector and generalized thresholding
Abstract—The Dantzig selector is a recently introduced technique for near-optimal estimatation of sparse signals from a limited set of measurements. This paper offers an interpre...
