2. 1. Energy Constrained Wireless Sensor Networks : Communication Principles and Sensing Aspects

   Author : Erik Björnemo; Anders Ahlén; Mikael Sternad; Erik Larsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; Signal processing; Signalbehandling;

   Abstract : Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. READ MORE

4. 2. Coordination and Self-Adaptive Communication Primitives for Low-Power Wireless Networks

   Author : Valentin Poirot; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-power Wireless Networks; IoT; Internet of Things; Synchronous Transmissions; Distributed Systems; Wireless Sensors Networks; DQN; Reinforcement Learning; WSN; Consensus;

   Abstract : The Internet of Things (IoT) is a recent trend where objects are augmented with computing and communication capabilities, often via low-power wireless radios. The Internet of Things is an enabler for a connected and more sustainable modern society: smart grids are deployed to improve energy production and consumption, wireless monitoring systems allow smart factories to detect faults early and reduce waste, while connected vehicles coordinate on the road to ensure our safety and save fuel.

5. 3. RF Wireless Power Transfer for IoT Applications

   Author : Morteza Tavana; Emil Björnson; Jens Zander; Ayça Özçelikkale; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic waste; Energy harvesting; Internet of things; transceivers; wireless power transfer; wireless sensor networks; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : With the emergence of the Internet of things (IoT) networks, the replacement of batteries for IoT devices became challenging. In particular, the battery replacement is more expensive and cumbersome for scenarios where there are many IoT devices; or where the IoT devices are in unreachable locations; or when they have to be replaced often.
