WSN Trends: Sensor Infrastructure Virtualization as a Driver Towards the Evolution of the Internet of Things

Fueled by advances in microelectronics, wireless communications and the availability of affordable mobile connectivity, the last decade has seen a rapid increase in the number of devices connected to the Internet. This evolution is part of the transition to the Internet of Things (IoT), which envisions connecting anything at any time and place. While it can be argued that the IoT is already here, the next paradigm shift is already emerging in the horizon, targeting yet another order of magnitude increase in the number of interconnected devices and promising to bring people and processes in the equation. However, before such a paradigm shift can be realized, significant challenges with respect to scalability, cooperative communications, energy consumption, as well convergence of sensor and analytics trends have to be resolved. Sensor Virtualization Technology capturing both the Virtual Sensors and Virtual Sensors Networks aspects is a promising paradigm that can pave the way towards this vision.
