  6. Research Sponsors NSF $4+ million current funding

  7. Dependable Distributed & NetworkedSystems Lab • Led by 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 • Embedded sensor networks • Internet-based distributed systems • Approach • Self-stabilization • Model-based control of systems (using formal methods) • Scalable network services

  8. DDNS Lab • Impact • Sensor network based classification and tracking of persons, persons carrying “guns”, cars, tanks; 2003 • Aladdin home networking system, built at Microsoft Research, showcased in PBS serial; 2000 • NetraProxy internet server, commercially sold by Sun; 1997 • Leader in self-stabilization • $2.4+M funding from DARPA for sensor networks research • $.5M funding from NSF for NASA dependability research • $200K funding from Microsoft Research for internet services research

  9. DDNS: Ongoing Activities • Focus on theoretical limits and algorithms for low power distributed computing/networking/sensing • Graph theoretic and geometric techniques, especially for large-scale systems and WSNs • Currently active projects apply ideas in experimental settings: • Cellphone based sensor networking projects (involving Motorola and Nokia) with focus on MAC, routing, localization • Security projects with java motes (involving SUN) and with ARO • Integrating sensor networks with enterprises (e.g. SENSORMAP, involving Microsoft) • High level programming languages (DESAL, with NSF) • OSU is a leader in wireless sensor network projects and facilities: • Kansei being expanded to include 1000 TMotes this fall, 100+ Imote2s, 100-200 SunSPOTs (planned) • 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 Networking • Led by 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

  11. Networking Research Lab • Current Research Activities • Formal methods for network protocol analysis • Internet security formal monitoring and measurement • Machine learning based approach for network protocol security analysis • Cyber infrastructure security protection • Network malicious node conviction • Internet attack trace back: single packet based approach • David Lee http://www.cse.ohio-state.edu/~lee/ • Networking Research Lab http://www.cse.ohio-state.edu/NRL/

  12. Sensor Networks and Mesh Networks • Led by Prasun Sinha http://www.cis.ohio-state.edu/~prasun • Goal: To design efficient next-generation wireless networks • Multi-Radio Networks • How can communication protocols of one radio-network leverage the other radio for improved performance? • Communication Protocols for Ad-hoc Networks • How do you design energy efficient protocols for unicast, broadcast, and network management in ad-hoc networks? • MAC and Routing Layers for continuously varying Channel Rates • How do you reduce the MAC overhead to improve performance? • How do you compute a route with the best end-to-end rate?

  13. Sensor Networks and Mesh Networks • Led by Prasun Sinha http://www.cse.ohio-state.edu/~prasun • Goal: To design scalable, robust, and efficient next-generation wireless networks • Project 1 (NSF): Energy Efficient Distributed Sensor Network Control [with Ness Shroff] • Project 2 (NSF): Tracking Movements with a Sparse Sensor Network • Project 3 (NSF): Mesh Network Protocols for Time Varying Channels

  14. Sensor Networks and Mesh Networks (contd.) • Recent Activities • Optimal Design of Network Protocols based on Channel Models • Delay Tolerant Networking for City-Wide Coverage with Sparse WiFi Deployment • Network Protocols for Rechargeable Sensor Networks • Note: PhD Students sought for all ongoing projects as well as recent activities

  15. Real-Time and Secure Communication Lab • Led by Dong Xuan http://www.cse.ohio-state.edu/~xuan/ • Research Interests: broadly in the areas of distributed systems and networking: • Scalable QoS control: We seek to build up an architecture and design/develop various algorithms and protocols to provide scalable QoS (deterministic and statistical) guarantees to real-time and mission critical applications in wired and wireless networks. • Security:We attempt to design and implement advanced defense systems to internet-wide Distributed Denial of Services attacks (DDoS) and active worm attacks. We are also interested in analyzing and improving the resilience of sensor networks to different types of attacks.
