Abstract:

The speaker with give a flavour of work going on at UPenn in the area of Embedded Realtime Systems in four broad areas as given below and focus on Networked Cyber Physical Systems with specific applications in the Automotive domain.

Networked Cyber-Physical Systems: As computing and communication get more tightly integrated into the physical processes around us, we are presented with new challenges of scale, robustness and complexity in sensor-actuator-controller wireless networks. This talk will cover three exciting research projects at the Real-Time & Embedded Systems Lab at the University of Pennsylvania.

FireFly ā€“ Real-Time Embedded Wireless Networks: We propose RT-Link, a time-synchronized link protocol for real-time wireless communication in industrial control, surveillance and inventory tracking. RT-Link provides predictable lifetime for battery-operated embedded nodes, bounded end-to-end delay across multiple hops, and collision-free operation. We investigate the use of hardware-based time-synchronization for infrastructure nodes by using an AM carrier-current radio for indoors and atomic clock receivers for outdoors.

EVM - Embedded Virtual Machines: As the links, nodes and topology of wireless systems are inherently unreliable, time-critical and safety-critical applications require programming abstractions where the tasks are assigned to the sensors, actuators and controllers as a single component rather than statically mapping a set of tasks to a specific physical node at design time. To this end, we introduce EVM, a powerful and flexible programming abstraction where virtual components and their properties are maintained across node boundaries.

AUTOMATRIX - Automotive Cyber-Physical Systems: The automobile of the future will be networked for network-based active safety and real-time traffic congestion probing and prediction. Automotive-CPS networks are a special class of networked Cyber-Physical Systems where the maximum relative speeds are in excess of 80m/s, the node density spans over 9,000 vehicles/km2 and, most importantly, the dynamics of the vehicle, the environment, driver reaction and interaction with other vehicles need to be considered in every communication and control decision.

Speaker Profile:

Rahul Mangharam is the Stephen J. Angello Chair and Assistant Professor in the Dept. of Electrical and Systems Engineering at the University of Pennsylvania. He is the Director of the Real-Time and Embedded Systems Lab at Penn. His interests are in real-time scheduling algorithms for wireless and embedded systems with applications in vehicular-to-vehicle networking, medical sensor networks and industrial control networks.

He received his Ph.D. in Electrical & Computer Engineering from Carnegie Mellon University where he also received his MS and BS in Electrical & Computer Engineering in 2007, 2002 and 2000 respectively. In 2002, he was a member of technical staff in the Ultra-Wide Band Wireless Group at Intel Labs. He was an international scholar in the Wireless Systems Group at IMEC, Belgium in 2003. He has worked on ASIC chip design at Marconi Communications (1999) and Gigabit Ethernet at Apple Computer Inc. (2000). He was a visiting researcher at Athens Institute of Technology, Greece in the summer of 2006.
