Capacity limits of cognitive radio with distributed and dynamic spectral activity
Abstract— We investigate the capacity of opportunistic communication in the presence of dynamic and distributed spectral activity, i.e. when the time varying spectral holes sense...

Designing Dynamic Interactive Visualisations to Support Collaboration and Cognition
Dynamic interactive visualisations (DIVs) are intended to help coordination and collaboration, through augmenting existing forms of synchronous communication (i.e. phones, face to...

Comparing a Cognitive and a Neural Model for Relative Trust Dynamics
Trust dynamics can be modelled in relation to experiences. Both cognitive and neural models for trust dynamics in relation to experiences are available, but were not yet related or...

Algorithms for Dynamic Spectrum Access with Learning for Cognitive Radio
We study the problem of dynamic spectrum sensing and access in cognitive radio systems as a partially observed Markov decision process (POMDP). A group of cognitive users cooperati...
