Sensing in IoT Era

Associate Director, Ottawa Carleton Institute for Biomedical Engineering, Canada

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.
