7. Dependable Distributed & NetworkedSystems LabFaculty: Anish Arora http://www.cse.ohio-state.edu/~anish/ • Central Goal • 99% users (including devices and businesses) should be able to communicate securely and reliably 99% of the time • requires scalable end-to-end dependability, which is still lacking • Focus • Large-scale wireless sensor networks • Internet-based distributed systems • Approach • Theory limits and graph/geometric algorithms for low power distributed computing/networking/sensing • Self-stabilization • Model-based control of systems (using formal methods)

8. DDNS Lab • Impact • Kansei interactive heterogenous large-scale WSN testbed; 2007 • ExScal and A Line In The Sand: sensor network based classification and tracking of persons, persons carrying “guns”, vehicles, tanks; 2004 • Aladdin home networking system, built at Microsoft Research, showcased in PBS serial; 2000 • NetraProxy internet server, commercially sold by Sun; 1997

9. DDNS Lab Current Status • Apply ideas in experimental settings: • Cellphone based sensor network project (involving Motorola/Nokia) with focus on MAC, routing, localization • Secure WSN fabrics, with Java motes (involving SUN) and with ARO • Integrating sensor networks with enterprises (involving Microsoft SensorMap) • High level programming languages (DESAL, with NSF) • OSU recognized as leader in WSN research and facilities: • Kansei being expanded to include 1000 TMotes, 100+ Imote2s, 200 SunSPOTs • ExScal remains among largest experiments conducted • ISS (Institute for Sensor Systems) has started operation, increasingly fellowships/internships support will be available through it, and an ExScal-like WSN project with Los Alamos is anticipated

10. Ad Hoc Mobile Wireless NetworkingFaculty: Steve Lai http://www.cse.ohio-state.edu/~lai/ • IEEE 802.11 is the most widely deployed standard for wireless LANs. We are interested in its scalability issue, i.e., we are aiming to answer the question: “Can they support large-scale, multi-hop ad hoc networks?” • Particularly, we are working on the following topics: • Is IEEE 802.11 scalable? • Time sync in multihop ad hoc networks • Is time sync essential for power saving? • Constructing connected dominating sets by way of clock synchronization • Coverage and Connectivity in Sensor Networks
