Dependable and Sustainable Cyber-Physical Computing – An Overview of IMPACT Lab’s Research


May 27, 2008


In this talk, I will review use-inspired research being conducted in the IMPACT lab at Arizona State University ( focused on novel secure, safe and energy-efficient (thermal-aware) adaptive solutions for cyber-physical applications of embedded and networked wireless sensors and actuators in various domains including pervasive healthcare, smart cargo containers, precision agriculture, and sustainable datacenter computing. Exemplar solutions include physiological value based key agreement scheme for body sensor networks, range-free localization using self organizing maps, and thermal-aware scheduling for data centers and biomedical sensor networks. These innovative solutions are being incorporated in software systems such as AYUSHMAN – a middleware for pervasive health monitoring and DO-COOL – thermal-aware (cool) resource management software for Datacenter Operation.


Sandeep Gupta

Sandeep K. S. Gupta is a Professor in the Department of Computer Science and Engineering at Arizona State University. Gupta has worked on several interesting problems in the domain of parallel and distributed computing and networking resulting in over 100 peer-reviewed publications. His recent work is focused on HER (Health – Energy – Reliability) computing and networking issues. He is best know for his work on block-cyclic distributed array expression compilation using virtual processor approach, EXTENT tool for automatic synthesis of parallel codes for block-recursive computations such as FFT using matrix tensor product based specification, symmetric key generation for body-sensor network using physiological signals (won a best paper award), context-aware middleware for pervasive computing, collective communication and synchronization on various parallel and distributed computing platforms, and thermal-aware scheduling for data centers and biomedical networks. Over the years his work has been supported by NSF, NIH, SFAz, Consortium for Embedded systems, Mediserve Inc, and Intel Corp. He is currently an associate editor for the IEEE Communication Letters and has co-authored the book: “Fundamentals of Mobile and Pervasive Computing,” McGraw Hill. Gupta was a TCP chair for GreenCom 2007 and BodyNets 2008. He heads the IMPACT lab in the Department of Computer Science and Engineering, School of Computing and Informatics at the Arizona State University.
