1. Synchronous Protocols for Low-Power Wireless: Towards Reliable and Low-Latency Autonomous Networking for the Internet of Things and Wireless Sensor Networks
Sammanfattning : With the emergence of the Internet of Things, autonomous vehicles and the Industry 4.0, the need for reliable yet dynamic connectivity solutions is arising.Many of these applications build their operation on distributed consensus. LÄS MER
2. Collaborative, Intelligent, and Adaptive Systems for the Low-Power Internet of Things
Sammanfattning : With the emergence of the Internet of Things (IoT), more and more devices are getting equipped with communication capabilities, often via wireless radios. Their deployments pave the way for new and mission-critical applications: cars will communicate with nearby vehicles to coordinate at intersections; industrial wireless closed-loop systems will improve operational safety in factories; while swarms of drones will coordinate to plan collision-free trajectories.

3. Enabling Scalable Security in Internet of Things
Sammanfattning : The popular notion of Internet of Things (IoT) implies two salient features: 1. a diversity of small things, i.e., constrained devices; 2. LÄS MER
4. Design and Identification of Wireless Transmitters for a Low-power and Secure Internet of Things
Sammanfattning : Wireless communication is a key enabler for connecting billions of Internet of Things devices. For networked embedded devices operating on limited energy resources, wireless communication dominates the power consumption. LÄS MER
5. Design and Performance of Diversity based Wireless Interfaces for Sensor Network Nodes
Sammanfattning : The main focus of the work presented in this licentiate thesis concerns antenna design, adaptive antenna control and investigation on how the performance of small wireless nodes can be increased by inclusion of multiple antennas. In order to provide an end-user suitable solution for wireless nodes the devices require both small form factor and good performance in order to be competitive on the marked and thus the main part of this thesis focuses on techniques developed to achieve these goals.
