  20. IPv6-based Grid Computing Projects • Telescience project allowed collaboration with the researchers in Argentina with their counterparts in Sweden to control the Intermediate Voltage Electron Microscope (IVEM 4000) in the USA. • This facility also allowed bioinformatic and collaborative visualization tools. • Incidentally, the Telescience project was also featuring an all-IPv6 native support-based underlying fabric. In that sense, it was interesting to see how the researchers approached the problem. • The researchers were able to transfer at the 1Gbps rate using this all-IPv6 infrastructure. • However, till date, no international project has attempted to capitalize on the experimental QoS features for which the IPv6 has good potential.

  25. Grid computing Architecture • Grids may be seen as made up of four layers : • Application layer (example: collaborative biomedical research) • Middleware layer (examples: Schedulers, APIs, Authentication schemes, Interfaces, Managing elements) • Computing Infrastructure layer (examples: PCs, PDAs, Mid-range and Mainframes, Supercomputers as individual nodes) • Distributed Communication / fabric layer (example: underlying networks) (c) Dr. Rahul Banerjee, BITS-Pilani, India

  26. The Grid-One Initiative at BITS-Pilani • BITS-Pilaniis currently involved in a two-part experimental project under its Grid-One Initiative: • In the first phase, it is building a medium-sized campus-wide grid involving • several Server-class systems, • about 3000+ PCs used inside the institute’s laboratories and faculty chambers, student hostel rooms and • many of the staff-owned PCs / Laptops / Tablet PCs etc. (The entire campus is connected using Gigabit Ethernet and Wireless LAN technologies.) • Operating Systems include Linux, FreeBSD, SCO Unix, HP-UX, Sun Solaris, Windows 2003 Server, Windows 2000/Me/XP, Novell Netware, Win CE <as client node>, Palm OS <as client node>. • The second phase would involve connecting the resultant grid to a bigger IPv6-enabled Grid for experimentation.

  27. Project BITS-LifeGuardA Wearable Computer Research Project for Saving Human Lives that uses native IPv6 (c) Dr. Rahul Banerjee, BITS-Pilani, India

  28. Introduction to the BITS Wearable Computing Project • The “Project BITS-WearComp” research programme • Conceptualized in 1999 • Started in the early 2000 • First white paper and roadmap published in 2001 • First specific project, the BITS-Lifeguard, begun in May 2001 <Blueprint discussed at the NGNi’s Brussels Meet in May 2001> • Objectives: • Saving human lives with the help of non-intrusive wearable computing devices • Using the advances in computer communication and networking technologies to complement the wearable device capabilities<including the native IPv6 support in the wearable as well as the car’s computer> (c) Dr. Rahul Banerjee, BITS-Pilani, India

  29. A little bit about the BITS-Lifeguard system • This research aims to protect human lives from those road accidents that result from the reduced levels of the physicalfitness or mental alertness of the driver. • Initially, it is focusing on light vehicles and their drivers / occupants. However, the concept is easily extensible to large vehicles and their drivers / occupants as well. • This research also draws on the works done by life scientists on human sensory system, brain and select externally measurable parameters (that can be measured, calibrated or accurately estimated without piercing human body). (c) Dr. Rahul Banerjee, BITS-Pilani, India

  30. Motivation behind the BITS-Lifeguard system • More people die of road accidents than due to natural calamities or other reasons • Out of these road accidents, as per various reports, • About 8% accidents were due to mechanical problems / failures in the vehicle • About 12% accidents were found to be due to traffic violations, wrong assessment of the situation-on-hand by the driver or activities that tend to distract drivers (including changing cassettes / CDs / speaking on mobile etc.) • Approximately, 73% of the accidents were attributed to the possibilities that the driver’s physical and mental alertness levels may have been unfit for driving at the time of accident • Remaining 7% accidents were accounted to various reasons including those of suicidal attempts / forced accidents etc. (c) Dr. Rahul Banerjee, BITS-Pilani, India

  31. The Vision behind the BITS-Lifeguard System (1 of 2) • The overall life-saving environment in which the BITS-Lifeguard is envisioned to work shall have two core components: • The wearable computing component: The BITS-Lifeguard • The vehicular computing component • The scenario of action would include: • Part-I: • sensing of select critical parameters that help estimate the current level of alertness and physical ability to drive safely, • comparing these with the pre-fed threshold levels and generate an alert to the driver; • in case, driver fails to respond quickly enough, send and SoS signal to the vehicular computer wirelessly These responsibilities are handled by the wearable computer (c) Dr. Rahul Banerjee, BITS-Pilani, India

  32. The Vision behind the BITS-Lifeguard System (2of 2) • The scenario of action would include: • Part-II • Taking over control from the driver, • Safely attempting to move the vehicle as per the pre-fed GIS map and GPS data • Stopping the vehicle on a side • Sending information wirelessly to the rescue / recovery agencies providing the location details, vehicle’s details and driver’s details • Intimating to the pre-registered relative / friend about the event and location These steps are taken by the vehicle’s computer (c) Dr. Rahul Banerjee, BITS-Pilani, India

  33. Elements of the BITS-Lifeguard Non-Intrusive Wearable Computing System • A wearable computing system of this category needs at least five basic elements: • Non-Intrusive Sensory elements to sense the wearer’s environment, • Computing elements to take care of computational needs; and, • Communication elements to interconnect these computing elements (with mobility) • Body safe Power Supply / Generation elements to provide the necessary power to the wearable computing system • Fabric or placeholder elements to allow interconnected elements in place <could server other purposes also> (c) Dr. Rahul Banerjee, BITS-Pilani, India
