Modelling the Performance of In-Call Probing for Multi-Level Adaptive Applications
Alan Bain,Peter Key +1 more
TL;DR: This paper derives analytic models, based on diffusion limits under a natural scaling, to quantify the benefits of in-call probing, and shows that this simple theory is remarkably accurate in predicting large-scale behaviour.

Dynamic decentralized multi-channel MAC protocols
TL;DR: These protocols build on slotted Aloha, but extend it in several ways to improve flow completion time and throughput, as follows: channels are assigned to flows rather than packets to eliminate per packet collisions, thus the total number of collisions is reduced.
Exploiting Channel Diversity in White Spaces
TL;DR: In this article, the problem of channel and rate selection for white-spaces was studied and a learning algorithm was proposed to minimize the regret with respect to a best or oracle-like algorithm.

Coalition Games and Resource Allocation in Ad-Hoc Networks
Richard J. Gibbens,Peter Key +1 more
TL;DR: This paper presents a series of experiments with several test networks that illustrate how a distributed scheme of flow control and routing can in practice be aligned with the Shapley values which capture the influence or market power of individual users within the network.

Sustainable capacity estimation
TL;DR: In this article, the authors use actively probing to estimate the sustainable capacity of the network and calculate a delay trend for each probe packet, which leads to estimate of the maximum network capacity and the background load on the network.
