Embedded Operating Systems for a Wireless Cellular Internet of Things (IoT) System - Tapa blanda

Sinopsis

Master's Thesis from the year 2017 in the subject Engineering - Computer Engineering, grade: 7.0, Vytautas Magnus University, course: M.Sc ELECTRONICS ENGINEERING, language: English, abstract: This thesis focusses on Embedded Operating Systems for a Wireless Cellular IoT System. Internet of Things (IoT) is a great chance for upcoming devices to be intelligent, more robust and efficient. This tremendous pathway has become available due to regular cost degradation of various separate systems and accessories like sensors, computing devices, communication methods, the cloud and the big data paradigms. Connectivity is the base for IoT and the type of access needed will focus on the nature of the application. Thus, the target is now on Narrow Band IoT, which is a Low Power Wide Area Network (LPWAN) radio technology standard that has been developed to contribute a wide range of devices and services to be connected via cellular telecommunications bands. Accordingly, the thesis works on ARM MBED OS, an embedded operating system, which is a platform as well as operating system for internet connected devices for 32-bit ARM cortex-M microcontrollers which is needed for NB-IoT system. First, MBED OS is designed and implemented on ARM cortex -M prototyping system MPS2+ as a real-time operating system by bringing latest version of CMSIS-RTOS with RTX as kernel on Cortex-M4 as well as its successor Cortex-M33 contained on MPS2+ hardware board to examine different RTOS parameters such as memory, heap, stack, hardware and software impacts. Next, these obtained parameters for MBED OS is compared with other RTOS, say FreeRTOS on MPS2+ board. Thus, the final outcome would be how cellular IoT system will change when a new embedded operating system will be incorporated into Corelink SSE 200 IoT subsytem and fulfil the requirements for NB-IoT standard.
