1. 21. Energy-Efficient Communication with Lightweight M2M in IoT Networks

   Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Carlos Gonzalo Peces; [2018]
   Nyckelord :IoT; LwM2M; low power consumption; TSCH; Contiki-NG; Eclipse Leshan.; IoT; LwM2M; låg energiförbrukning; TSCH; Contiki-NG; Eclipse Leshan.;

   Sammanfattning : OMA’s Lightweight Machine to Machine (LwM2M) is an application protocol for device management in the Internet of Things (IoT) that has been recently published and widely adopted in a lot of projects. The protocol is designed to operate in sensor networks and machine-to-machine environments, where one of the main constraints is the energy consumption since the nodes are usually battery powered.

3. 22. Radio Link Quality in Backscatter Communication

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Georgios Theodoros Daglaridis; [2018]
   Nyckelord :;

   Sammanfattning : The opportunities that the Internet of Things (IoT) offers impose the need of ultra low-power communication systems. For that, backscatter communication can be used, where the transmitting node consumes only a few tens of micro Watts. LÄS MER

4. 23. Timing delay characterization of GNU Radio based 802.15.4 network using LimeSDR

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

   Författare :Saptarshi Hazra; [2018]
   Nyckelord :Software Defined Radio; LimeSDR; GNU Radio; Latency; IEEE 802.15.4; USB Transfer Delay; USBMon; Software Defined Radio; LimeSDR ; GNU Radio; Latency ; IEEE 802.15.4; USB Transfer Delay;

   Sammanfattning : Massive deployment of diverse ultra-low power wireless devices necessitates the rapid development of communication protocols. Software Defined Radio (SDR) provides a flexible platform for deploying and evaluating real-world performance of these protocols. But SDR platform based communication systems suffer from high and unpredictable delays. LÄS MER

5. 24. OpenThread vs. Contiki IPv6 :An Experimental Evaluation

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Christoph Ellmer; [2017]
   Nyckelord :;

   Sammanfattning : Low-power wireless networks based on the IEEE 802.15.4 standard are widely used for emerging Internet of Things applications. So far, however, there is no standard network stack for such networks. LÄS MER

7. 25. The effect of network coexistence on the performance of wireless sensor networks

   Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

   Författare :Oriol Ros Fornells; [2016]
   Nyckelord :Wireless Sensor Network; IEEE 802.15.4; Castalia; Network coexistence; Beacons collisions; trådlösa sensornätverk; IEEE 802.15.4; Castalia; för samexisterande nätverk; beacon kollision;

   Sammanfattning : With the coming growth in Internet of Things (IoT) applications, we can expect environ-ments with many independent networks operating in nearby locations. Wireless Sensor Networks (WSN), which have become popular during the last few years, are the main type of networks used in IoT. The IEEE 802.15. LÄS MER
