Prof. Jaafar Elmirghani is a Fellow of IEE and InstP, and was appointed to a chair in Communication Networks and Systems at the School of Electronic & Electrical Engineering of the University of Leeds in 2007.
Power saving in communication networks is proposed through optimum end-to-end resource allocation. Currently, networks are typically three to five times over-provisioned to maintain QoS. This over-provisioning can be reduced (while maintaining QoS) through the optimisation of resource allocation in a real time fashion following demand and the availability of energy (e.g. renewable). Wake up on demand algorithms, dynamic buffer management, optimum content caching and the optimum allocation of resources such as processing, storage, switching and routing can lead to power saving.
