The Systems Research Group- a brief overview
Jon Crowcroft20.10.2010
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…)
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• Eiko Yoneki: Complex Dynamic Systems• Phillip Watts: Interconnects
Steven HandVirtualization, 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)
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
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
Jon CrowcroftEverything 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
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)

Some Specific Projects
• C-Aware - – with China Mobile
• Smart Social Signage - – with various (MSR SORA + HK video s/w)
• London Olympics – user contrib p2p/ad hoc video sharing 1M users
Models of Industry Collaboration
• Anything you can think of• Collaborate in research project – Contribute work/people/in kind
• Hire people from here - e.g. by trying them– Fund Students/Staff– Industry club
• IPR – We own, you own, we share - pick one– Cost varies in obvious way
