   University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Author : Khalil Mardini; Emad Abdulsamad; [2023]
   Keywords : Routing protocol for low-power and lossy networks RPL ; Wireless Sensor Networks WSN ; The Internet of Things IoT ; Objective Function OF ; Low-Power and Lossy Networks LLNs ; Expected Transmission Count ETX ; Min- imum Rank with Hysteresis Objective Function MRHOF ; Packet Delivery Ratio PDR ; Directed Acyclic Graph DODAG ;

   Abstract : The use of Internet of Things systems has increased to meet the need for smart systems in various fields, such as smart homes, intelligent industries, medical systems, agriculture, and the military. IoT networks are expanding daily to include hundreds and thousands of IoT devices, which transmit information through other linked devices to reach the network sink or gateway. READ MORE

3. 2. UWB-based wireless sensor network with medical application

   University essay from Uppsala universitet/Signaler och System

   Author : Joakim Lindström; [2018]
   Keywords : ;

   Abstract : This master thesis aims to develop a prototype of a wireless sensor network (WSN) using ultra wideband (UWB) radio and communication. The WSN consists of five sensor nodes and one sink which is connected to an Android smartphone. The smartphone acts as a sensor data management unit and has the ability to display sensor measurements. READ MORE

4. 3. A Proxy for Distributed Hash Table based Machine-to-Machine Networks

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Daoyuan Li; [2011]
   Keywords : M2M; P2P; DHT; Proxy; Gateway; Zigbee; 6LoWPAN; CoAP; Cache;

   Abstract : Wireless sensor networks (WSNs) have been an increasingly interest for both researchers and entrepreneurs. As WSN technologies gradually matured and more and more use is reported, we find that most of current WSNs are still designed only for specific purposes. READ MORE

5. 4. Cognitive WSN access based on local WLAN traffic estimation

   University essay from KTH/Kommunikationsnät

   Author : Marcello Lagana; [2011]
   Keywords : ;

   Abstract : The recent growth in the deployment of wireless networks that access the unlicensed ISM bands has introduced the issue of co-existence between different kinds of wireless technologies. In this work we address the enhancement of the performance of the low-cost Wireless Sensor Network nodes competing for spectrum access with the WLAN devices, that are more powerful in terms of transmission and computational power.
