  3. 2. UWB-TWR performance comparison in a hybrid node network

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

    Author : Oskar Sundin; [2021]
    Keywords : UWB; TWR; CSMA; Token ring;

    Abstract : This thesis investigated the performance of a positioning system that utilised UWB technology where devices regularly shifts between acting as an initiator and as a responder for distance measurements between each other. The goal was to investigate existing positional techniques and to implement a novel network where devices initiates and responds to distance measurement exchanges. READ MORE

  4. 3. A Modeling Language for Timed Automata

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

    Author : Ernst Widerberg; [2021]
    Keywords : ;

    Abstract : This work details the design and implementation of a modeling language for timed automata. The primary intended use of the language TML is as an interface to controller synthesis system m2mc, which is being developed in a current KTH/Chalmers research project. READ MORE

    Abstract : Denna rapport behandlar prestandaproblem i den nyligen standardiserade Mesh kommunikationsstandarden (IEEE 802.11s). I denna rapport, undersöker och förbättra vi ett förhållande som resulterar i reduktion av genomströmningen i en kedja av noder topologi. IEEE802. READ MORE

  6. 5. Performance Evaluation of MAC protocols in Wireless Sensor Networks

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Mattias Orell; [2016]
    Keywords : ;

    Abstract : Wireless Sensor Networks have limited resources in terms of processing capability, battery power, and channel bandwidth, which makes them both lightweight and cheap. These limitations and also advantages come with some problems regarding network lifetime and fault tolerance, as the nodes share the same wireless media with WiFi, Bluetooth and microwaves. READ MORE
