Industry estimates predict there will be over 20 Billion Internet of Things (IoT) devices shipping by the year 2020 (source: Gartner.com). Most IoT devices will involve some type of network connectivity (e.g., WiFi, Bluetooth LE, Zigbee, 6LoWPAN, Ethernet), and many also will include a Graphical User Interface (GUI). These devices usually also perform some functions other than network communication and user interaction, such as data acquisition (sensors), appliance control (home automation), and DSP (security systems). Because of this processor load, all but the simplest IoT devices will require 32-bit microprocessors/microcontrollers in order to provide the necessary address space and processing power. There already is strong migration from 8-bit and 16-bit to 32-bit microprocessors, due to requirements for enhanced device functionality as well as the attractive cost/performance attributes of new 32-bit microprocessors. The predicted IoT growth promises to sharply accelerate this migration! The migration to 32-bit processors is clear, but what about the software side? Research to identify a suitable OS for such IoT devices. Justify your answer with relevant examples. include text citations and corresponding references
