Mobile technologies have inspired the emergence of novel cyber-physical systems, ranging from mobile networking to vehicular to health and medicine. The integration of Internet with networked devices, people and physical systems provides a promising vision of smart mobile systems enabled by the Internet-Of-Things (IoT) framework. The decentralized, heterogeneous and relatively large-scale nature of IoT brings about challenges in realizing reliable wireless networking and efficient computing in such mobile-IoT systems. In this talk I will discuss my research on emerging technologies that can shape mobile-IoT systems design and help address the communication and computing challenges to build next–generation smart mobile ubiquitous systems. In particular, I will introduce a novel concept called visual MIMO that advocates the use of cameras for communication, where cameras can be used as receivers for information communicated through light. I will also discuss how mobile applications running on vehicular on-board units (OBU) can be made more computationally efficient through cloud-computing. Finally, I will discuss the research agenda for our newly established Mobile Cyber-Physical Systems Lab at Georgia State University.
Ashwin Ashok is currently an Assistant Professor in the Dept. of Computer Science at Georgia State University where he leads research on mobile systems and Internet-of-Things. Prior to this he was a Postdoctoral Research Associate in ECE at Carnegie Mellon University under the mentorship of Prof. Peter Steenkiste (CMU) and in collaboration with Dr. Fan Bai (GM Research). While affiliated to the CMU-GM Continuous and Autonomous Driving Collaborative Research Lab (CRL) at CMU he developed cloud-computing systems for vehicular applications. Ashwin completed his Ph.D. in Oct'2014 from Wireless Information Network Lab (WINLAB) at Rutgers University where he worked under the guidance of Profs. Marco Gruteser, Narayan Mandayam and Kristin Dana. His doctoral thesis developed a novel inter-disciplinary concept called visual MIMO that explores the use of cameras and other optical arrays as receivers in a communication system. Ashwin has interned at QualComm (NJ) for a summer working on QualComm’s LumiCast technology for visible light communication based indoor positioning. Ashwin is an experimentalist and has keen interests in system design and prototyping. He loves tinkering with circuits, Arduino and RaspberryPi and plays cricket, chess and badminton in his leisure.
