4. 3. Design Guidelines of A Low Power Communication Protocol for Zero Energy Devices

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jiayue Zhang; [2023]
   Nyckelord :Energy efficient communication protocol; sensor data transfer; zero energy devices; battery-less; energy harvesting; Energieffektiv kommunikationsprotokoll; sensordatöverföring; “zero” energienheter; batterifria; energy harvesting;

   Sammanfattning : Lågströmskommunikationsprotokoll såsom 6LoWPAN har använts i stor utsträckning för applikationer som kräver mindre energiförbrukning för trådlös kommunikation på korta avstånd, exempelvis IoT-enheter. Eftersom antalet sådana enheter ökar blir det allt viktigare att överväga ambient energy harvesting som en energikälla för att driva sådana enheter. LÄS MER

5. 4. Backscatter Communications for 6G

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Lakshmi Rajeev Cheekati; Jin Yan; [2022]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

   Nyckelord :Gotland; Östergarnslandet; Polygeneration system; Homer Pro; Solar PV; Wind power; Energy storage; Battery; Hydrogen; Flywheel; Redox Flow battery; Pumped Hydro; Sustainable development.; Gotland; Östergarnslandet; Poly-genererings system; Homer Pro; Solceller; Vindkraft; Energilagring; Batterier; Vätgas; Svänghjul; Redox Flödesbatteri; Pumpkraftverket; Hållbar utveckling.;

   Sammanfattning : The project Austerland Energi at the eastern tip of the island of Gotland called Östergarnslandet was started as a response to the larger project Omställning Gotland funded by the Swedish government as an effort for a pilot project to convert to renewable energy to reach zero CO2-emissions for the country in 2045. The current plan for the Austerland energy system is a solar PV and wind production base with energy storage in the form of batteries and hydrogen which also can be used as vehicle fuel. LÄS MER
