  1. 1. 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

  5. 4. Media Access Control for Wireless Sensor and Actuator Networks

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Muaz Un Nabi; [2012]
    Keywords : NS-2; WSN; IWLAN; DCF; PCF;

    Abstract : In a wireless network, the medium is a shared resource. The nodes in the network negotiate access of the shared resource using the Medium Access Control (MAC) protocol. The design of a MAC protocol for a sensor node is not the same as that for a wireless transceiver. READ MORE

  6. 5. Implementation of Collection Tree Protocol over WirelessHART Data-Link

    University essay from JTH, Data- och elektroteknik

    Author : Kiran Kumar Koneri; [2011]
    Keywords : WSN; WirelessHART; Time Synchronization Channel Hopping; Collection Tree Protocol; Reliability; Efficiency;

    Abstract : Wireless Sensor Networks (WSNs) are ad-hoc wireless networks for small form-factor embedded nodes with limited memory, processing and energy resources. Certain applications, like industrial automation and real-time process monitoring requires time synchronized reliable network protocol. READ MORE
