Title: Trade-offs between Energy Consumption and QoS in Systems and Networks
Presented by: Prof. Erol Gelenbe, Imperial College London
Abstract: According to some reports, ICT comes at the cost of electricity consumption worldwide which is at a par with the total electrical energy consumption of Japan plus Germany, of the order of 1500 TWH per year. Thus as we wait for new technologies which may reduce this number considerably, we have to think carefully about how we can consume less energy for computing and communications. Using practical examples drawn from our research, based on measurements and models, we will discuss how we can affect the trade-off between QoS and energy consumption in computer systems and networks and address some novel models and performance that analyse renewable energy using the concept of an Energy Packet Network (EPN) where energy units are generated, stored in discrete units and forwarded on demand. We will present new analytical models for the interaction between computation, communication and energy consumption and also discuss the possibility of using spin properties of particles for network communications. The presentation is based on the speaker’s recent papers that have appeared in IEEE Access, ACM Ubiquity, IEEE Trans. on Emergin Topics in Computing, ACM Performance Evaluation Review, and the journal Energies.
Biography: A native of Turkey and Fellow of ACM and IEEE, the speaker received the ACM-SIGMETRICS Life-time Achievement Award for pioneering work and leadership in computer and network performance evaluation. He was elected to the Royal Academy of Sciences, Arts and Letters of Belgium (2015), the Science Academies of Hungary (2010), Poland (2013) and Turkey (2007), and the 350 member French National Academy of Engineering (2008). He is ranked among the “Top 50 PhD advisers worldwide and all times” by the American Mathematical Society’s Math Genealogy Project, and has graduated 73 PhDs including 17 women. He was awarded Knight of the Legion of Honour (2014) by the President of France and Commander of Merit (2005) by the President of Italy. His other awards include three honorary doctorates (“honoris causa”), the Dennis Gabor Award of the Hungarian Academy of Sciences (2013), and the Grand Prix France Telecom of France (1996). His research is currently funded by EPSRC (similar to NSF), the European Union, and industry.
