1. 1. Control system and simplified timesynchronization for heterogenous IoT systems with medium time requirements

   University essay from KTH/Hälsoinformatik och logistik

   Author : Jemma Touma; Simon Hejdenberg; [2024]
   Keywords : Internet of Things; time synchronization; wireless sensor networks; network time protocol; Android; Bluetooth; WiFi Direct;

   Abstract : The company QTPIE conducts research on drivers and their unconscious reactions when driving. To help, they use smart devices that today must be individually handled at the start and end of a run, and have individually set timestamps, which can lead to differences between the units when data is entered and collation of the units' data after a run.

3. 2. Energy Efficient Communication Scheduling for IoT-based Waterbirds Monitoring: Decentralized Strategies

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Otabek Sobirov; [2022]
   Keywords : TSCH; 6TiSCH; RPL; scheduling; energy consumption; COOJA; autonomous scheduling; distributed scheduling; reinforcement learning; RL-based scheduling; Q-Learning;

   Abstract : Monitoring waterbirds have several benefits, including analyzing the number of endangered species, giving a reliable indication of public health, etc. Monitoring waterbirds in their habitat is a challenging task since the location is distant, and the collection of monitoring data requires large bandwidth.

4. 3. Task Scheduling Using Discrete Particle Swarm Optimisation

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Hampus Karlberg; [2020]
   Keywords : Scheduling; Discrete Particle Swarm Optimisation; Wireless Networks; Meta Heuristic; Machine Learning; Schemaläggning; diskret Particle Swarm Optimisation; Trådlösa Nätverk; Metaheurestik; Maskininlärning;

   Abstract : Optimising task allocation in networked systems helps in utilising available resources. When working with unstable and heterogeneous networks, task scheduling can be used to optimise task completion time, energy efficiency and system reliability. The dynamic nature of networks also means that the optimal schedule is subject to change over time. READ MORE

5. 4. Context-Based Authentication and Lightweight Group Key Establishment Protocol for IoT Devices

   University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

   Author : Nico Ferrari; [2019]
   Keywords : Internet of Things; Context-based authentication; Fuzzy commitment scheme; Cryptographic key establishment; Lightweight cryptography; Contiki; One-way accumulators;

   Abstract : The concept of the Internet of Things is driven by advancements of the Internet with the interconnection of heterogeneous smart objects using different networking and communication technologies. With the rapidly increasing number of interconnected devices present in the life of a person, providing authentication and secure communication between them is considered a key challenge. READ MORE

6. 5. Dynamic Bandwidth Allocation for Wireless Nodes with Software Defined Networking in Heterogeneous Networks with Embedded Systems

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Thomas Jädal; Dirk Postol Dissel; [2019]
   Keywords : ;

   Abstract : In the wireless computer networks of today, there is a limitation on how wireless access points handle bandwidth distribution to wireless nodes, both in Software Defined Networking (SDN) solutions, traditional networks with routers and switches, and in embedded systems. The limitation is the lack of control of the node bandwidth usage. READ MORE
