22. IoT Latency and Power consumption : Measuring the performance impact of MQTT and CoAP
University essay from Högskolan i Jönköping/JTH, Datateknik och informatikAbstract : 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.

24. Thermal energy harvesting for indoor industrial applications
University essay from Mittuniversitetet/Avdelningen för elektronikkonstruktionAbstract : Wireless sensor network (WSN) nodes cannot directly used by the traditional power grid, a most common way to supply power to WSN nodes is to use batteries. However, the battery has a disadvantage that is the limited lifetime, adding an energy harvester to extend the lifetime is a good way. READ MORE

25. Publish-Subscribe Communication for CoAP
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : Low powered Internet of Things solutions such as wireless sensor networks often operate under heavy constraints, and require special care in the design of their communication models. This project consists of implementing and evaluating the proposed IETF draft of the publish-subscribe communication model for the Constrained Application Protocol (CoAP) on a wireless sensor network (WSN) using the Contiki operating system.
