1. The Systems Research Group - a brief overview Steven Hand 14th December 2009

2. Systems Research Group Activities The SRG designs and builds systems: – We design and build computer systems – We design and build operating systems – We design and build network systems – We design and build distributed systems (many of us also investigate the theoretical and/or analytical underpinnings of these…)

3. SRG People Jean Bacon: distributed systems and middleware Jon Crowcroft: networking the mobile masses Richard Gibbens: modeling networks David Greaves: safety-critical ubiquitous systems Tim Griffin: algebras and languages for routing Steve Hand: virtualization, storage and multi-core Ian Leslie: mobile operating systems & networks Cecilia Mascolo: mobile and sensor systems Derek McAuley: distributed systems design Andrew Moore: better networks thru measurement

4. Steven Hand Virtualization, Storage and Multi-core Xen: open-source virtualization – Fault-tolerance via deterministic replay Horizon: storage for ubiquitous systems – Availability, differential privacy, economics Multi-core: – Software lock-elision (transparently scale apps) – Symphony OS (speculative execution)

5. Andrew W Moore Measurement-Informed Network Design Designing and building new network systems using recent photonic breakthroughs Beyond 100Gb/s: converged architectures for end-hosts and networks Energy-Proportional Networking: whole-system, top-to-bottom redesign 3M: measuring, monitoring, modeling networks

6. Jean Bacon Systems for Health and Transport PAL: health and lifestyle monitoring – seamless support for assisted living SmartFlow: secure event-driven middleware – healthcare applications (audit, anomaly detection, …) TIME-EACM: monitoring trains, buses, traffic, e.g. – MIDAS data mining (M25 induction loop) – low impact infrared lamp-post sensors

7. Jon Crowcroft Everything Networking Haggle: ad hoc google (and other applications…) SocialNets: leveraging social networks for comms – predictive content dissemination, routing, … ITA: bullet-proof ad-hoc networking TINA: how do we make an airport work better? – passive RFID boarding pass, bag check: 1M objects @ 1m! Horizon: making pervasive computing make money – Welcoming city, Connected journey, A Day in the Park

8. Cecilia Mascolo Mobile and Sensor Systems Content dissemination via opportunistic communication – Sharing media content during transport journeys Social network analysis (with time and space) – Human connectivity and patterns analysis – Applications: adverts; content dissemination; provisioning Wildlife monitoring through mobile sensors – Tagged animals to understand behaviour and patterns Mobile sensing of human activity through mobile phones – Exploiting sensors on phones to gather behaviour, interactions/emotions (in collaboration with social psychology)
