Design and Implementation of Fault-Tolerant Firmware Updating Methods for Time-Critical Battery Products

Scheduling in Multi-Radio Sensor System Connecting ZigBee with Bluetooth Low Energy

In this work two radios with heterogeneous characteristics have been paired to enable mobile sensor nodes to achieve a significantly higher reliable connectivity at a lower total energy cost, compared to a single radio. A Patient Monitoring Network (PMN) is developed to elucidate the need for a multi-radio platform. Nordic's nRF51822 Bluetooth...

Wireless Powered Smart Homes: Creation of a WiFi powered smart climate ecosystem

Wireless energy is found to be an enabler for IoT in smart homes. WiFi signals can be used as an energy source to power connected climate sensors. The smart climate product ecosystem is designed and a business model is created as part of an overall implementation startegy.

Robust Downstream Communication and Storage for Computational RFIDs

Computational RFID (CRFID) devices are emerging platforms that can enable perennial computation and sensing by eliminating the need for batteries. Although much research has been devoted to improving upstream (CRFID to RFID reader) communication rates, the opposite direction has so far been neglected, presumably due to the difficulty of...

Wirelessly Powered Non-Volatile Memory

Content creation and content sharing have become part of our daily lives. With modern electronics, creating and sharing content has become very convenient, but this convenience has come at a price. Devices like smartphones that enable us to easily share content, are costly and complex. Devices like USB flash drives, on the other hand, are low...

A Comprehensive Study of Passive Wake-up - Radio in Wireless Sensor Networks

Wake-up radio, as a secondary radio transceiver, is implemented to monitor the channel condition so that the main radio can be turned o when there is no communication activity. This thesis work focuses on the analysis of passive wake-up radio (PWUR), where the wake-up radio is entirely powered by the wake-up signal and does not need any...

Cognitive Radio Design: An SDR Approach

Cognitive Radios are currently a big challenge for the telecommunications industry. Many efforts are in progress to make communication radio systems as adaptive as possible such that they are aware of their environment and they are self configurable. An ultimate adaptive radio with the specified features is used to be called a Cognitive Radio. A...
