Center node: "towards a practical architecture for india centric internet of things"
  Abstract: An effective architecture for the Internet of Things (IoT), particularly for an emerging nation like India with limited technology penetration at the national scale, should be based on tangible technology advances in the present, practical application scenarios of social and entrepreneurial value, and ubiquitous capabilities that make the realization of IoT affordable and sustainable. Humans, data, communication and devices play key roles in the IoT ecosystem that we perceive. In a push towards this sustainable and practical IoT Architecture for India, we synthesize ten design paradigms to consider.
