The concept of sensors, instrumentation and measurement, signal and image processing is undergoing many changes due to the advent of IoT. The idea of “whatever can be measured”, “wherever can be measured,” “whenever can be measured” has challenged the researchers to re-examine how sensing is done, sensed data is managed and information is extracted. IoT demands the sensors to be cheaper so that they can be easily deployed, be physically “small” and unobstrusive, be wireless and communicate “on demand” and “at will”, consume less power (“green”), preprocess the data before communicating, self identify and self validate, self calibrate and, be fault tolerant. Sensing smartly becomes crucial in this IoT Era. IoT also demands that there be “intelligence” at sensing, communicating and processing levels. Important issues from the signal processing perspective include quantity and quality of sensed data. Quality is dependent on the type of sensing (contact or non-contact) while quantity may be attributed to ubiquitous nature of sensing. Quantity and quality of sensed data affect the extraction and interpretation of information. When processing is outsourced, issues of privacy and security also need to be addressed.
Prof. Sreeraman Rajan is a Canada Research Chair in Sensor Systems in the Department of Systems and Computer Engineering in Carleton University, Ottawa, Canada since 2015. He is also currently the Associate Director, Ottawa Carleton Institute for Biomedical Engineering. Before joining Carleton University, he was with Defence Research and Development Canada (DRDC) Ottawa, Canada as a Senior Defence Scientist. He has worked in the areas of nuclear science and engineering, control, electronic warfare, communication and biomedical engineering while in industry. He is currently the Chair of the IEEE Ottawa EMBS and AESS Chapters. He has served IEEE Canada as its board member (2010-Oct 2018) and the IEEE MGA in its Admissions and Advancement Committee, Strategic and Environment Assessment Committee. He was awarded the IEEE MGA Achievement Award in 2012 and recognized for his IEEE contributions with Queen Elizabeth II Diamond Jubilee Medal in 2012. IEEE Canada recognized his outstanding service through 2016 W.S. Read Outstanding Service Award. IEEE Ottawa Section recognized him as an Outstanding Volunteer in 2012 and an Outstanding Engineer in 2018. He has been involved in organizing several successful IEEE conferences and has been a reviewer for several IEEE journals and conferences. He is the holder of two patents and two disclosures of invention. He has authored more than 150 journal articles and conference papers. He is a Senior Member of IEEE, a member of IEEE Instrumentation and Measurement, Engineering in Medicine and Biology, Signal Processing and Aerospace and Electronic Systems Societies.
