2. 1. Using Existing Infrastructure as Support for Wireless Sensor Networks

   Author : Jonas Neander; Mats Björkman; Mikael Nolin; Jukka Mäki-Turja; Björn Knutsson; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; wireless; sensor networks; communication; base station; asymmetric communication; multihop; network lifetime; Computer science; Datavetenskap; Datavetenskap;

   Abstract : Denna avhandling handlar om hur befintliga datorinfrastrukturer i t.ex. sjukhus och industrier kan avlasta sensornätverk med energikrävande uppgifter. Vi har forskat på olika aspekter som gör det möjligt att förlänga livslängden på dessa sensornätverk. READ MORE

4. 2. Security and Self-stabilization in Sensor Network Services

   Author : Andreas Larsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Clock-synchronization; Secure and Resilient Computer Systems; Ad-hoc Networks; Self-Stabilization; Sensor-Network Systems; Clustering;

   Abstract : Wireless sensor networks consist of small sensor nodes that monitor their environment and that together can cover vast geographical regions. It is a promising field with many possible applications in different application areas. Typically the nodes do not have any preexisting information about the network topology when deployed.

5. 3. Characterization of Single- and Multi-antenna Wireless Channels

   Author : Shurjeel Wyne; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; channel measurements; channel modeling; Wireless propagation; sensor networks;

   Abstract : The wireless propagation channel significantly influences the received signal, so that it needs to be modeled effectively. Extensive measurements and analysis are required for investigating the validity of theoretical models and postulating new models based on measurements. Such measurements, analysis, and modeling are the topic of this thesis. READ MORE

6. 4. Resource-Aware and Personalized Federated Learning via Clustering Analysis

   Author : Ahmed Abbas Mohsin Al-Saedi; Veselka Boeva; Emiliano Casalicchio; György Dán; Blekinge Tekniska Högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Federated Learning; Clustering Analysis; Eccentricity Analysis; Non- IID Data; Model Personalization; Computer Science; Datavetenskap;

   Abstract : Today’s advancement in Artificial Intelligence (AI) enables training Machine Learning (ML) models on the daily-produced data by connected edge devices. To make the most of the data stored on the device, conventional ML approaches require gathering all individual data sets and transferring them to a central location to train a common model.
