Abstract

Rapid miniaturization has led to the size of unit computing approaching virtually zero. In foreseeable future, Computing will be all around us, in mostly invisible forms, and is expected to lead 50+ billions of IoT (Internet of Things) devices. At the forefront of which will be distributed sensing nodes acting as the eyes and ears of IoT, which needs to be incorporate intelligence to go from data domain to information domain closer to the edge of the network. Tight resource constraints of these devices in terms of form-factor and energy-availability calls for order(s) of magnitude of improvement of energy-efficiency of computing and communication in a sensor node. In this talk we will highlight how a Secure Human-Centered Network of Intelligent Devices can be employed using multiple on-body sensors and a body hub connected to the cloud by efficiently incorporating (1) Staged Inference i.e. distributing the analytics in a hierarchical manner from sensors to hub to could and (2) Human Body Communication that uses the conductive properties of the human body to securely interconnect devices in and on the body with >100x better energy-efficiency compared to WBAN.
