1. 1. Designing a communication controller for a wireless sensor network : Practical considerations and comparisons

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

   Author : Frej Larssen; Axel Karlsson; [2023]
   Keywords : Wireless sensor networks; IoT; LTE-M; Comparison; Trådlösa sensornätverk; IoT; LTE-M; Jämförelse;

   Abstract : As the use of Internet of Things (IoT) devices increases, so does the number of available hardware platforms. Today there exists a broad range of hardware components that could be used to develop an IoT product and selecting the right ones is a difficult task. READ MORE

3. 2. Detecting and identifying radio jamming attacks in low-power wireless sensor networks

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

   Author : John Kanwar; [2021]
   Keywords : ;

   Abstract : Wireless sensor networks (WSNs) are used in all kinds of different sectors ranging from agriculture, environment, healthcare and the military. Embedded systems such as sensor nodes are low-power and consist of low memory, which creates a challenge for its security. One of WSN’s worst enemies is interference radio jamming attacks. READ MORE

4. 3. Battery Driven Embedded System for Indoor Localization of Pneumatic Tools

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

   Author : Kajsa Hjort; [2020]
   Keywords : Wireless localization; Internet of moving technology IoMT ; Sensor system; Industry 4.0 andWireless Sensor Networks WSN ; Trådlös lokalisation; Internet avMoving Things; sensorsystem; smarta system och trådlöst sensornätverk;

   Abstract : As the rapid progress in technology changes our daily life, it also changes how the Industry works. The new developments enable technologies such as the Internet of Moving Things (IoMT), and through these technologies, new challenges arise. IoMT adds one more vital issue, localization, to be solved in comparison to the Internet of Things (IoT). READ MORE

5. 4. A CoAP Publish-Subscribe Broker for More Resource-Efficient Wireless Sensor Networks

   Abstract : With the rapid development of the Internet of Things, Wireless Sensor Networks (WSNs) are deployed increasingly all over the world, providing data that can help increase sustainable development. Currently in Uppsala, Sweden, the GreenIoT project monitors air pollution by using WSNs. READ MORE

6. 5. IoT Latency and Power consumption : Measuring the performance impact of MQTT and CoAP

   University essay from Högskolan i Jönköping/JTH, Datateknik och informatik

   Author : Alexander Lagerqvist; Tejas Lakshminarayana; [2018]
   Keywords : Internet of things; IoT; Wireless sensor networks; WSN; Constrained devices; MQTT; CoAP; Latency; Power consumption; Experiment;

   Abstract : The purpose of this thesis is to investigate the impact on latency and power consumption of certain usage environments for selected communication protocols that have been designed for resource constrained usage. The research questions in this thesis is based on the findings in Lindén report “A latency comparison of IoT protocols in MES” and seeks to answer the following: ”How does MQTT impact the latency and power consumption on a constrained device?” ”How does CoAP impact the latency and power consumption on a constrained device?” ”How does usage environment influence the latency for MQTT and CoAP?” This thesis only seeks to explore concepts and usage environments related to wireless sensor networks, internet of things and constrained devices.
