  1. 6. Bluetooth Low Energy Industrial Sensor

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Lamiaa Riad; Haithem Elhesseawy; [2018]
    Keywords : Bluetooth; BLE; Sensor; IoT; RSSI; Machines; Path Loss; Line of Sight; Mesh Network; Non Line of Sight; Technology and Engineering;

    Abstract : Industrial Internet of Things (IIoT) market is rapidly growing and expected to further expand in the incoming years. To keep up with such a fast pace, new wireless technologies need to be developed to accommodate the huge number of devices expected to connect to the internet. READ MORE

  3. 7. Distributed Device Synchronization

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Mahmoud Malekighaleabdolreza; [2018]
    Keywords : ;

    Abstract : Generally, synchronization in Wireless Sensor Networks (WSN), allows successful and accurate communication between nodes to occur. Each node in WSN runs independently and have its own clock which can drift from the other device’s clock. READ MORE

  4. 8. Time-synchronized wireless mesh networks using battery-powered nodes

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

    Author : Leif Karlsson; [2018]
    Keywords : wireless sensor network; sensor node; mesh network; time synchronization; sleep mode; battery life;

    Abstract : This thesis proposes an implementation of battery-powered, time-synchronized wireless nodes that can be deployed in a wireless network topology. Wireless sensor networks are used in a wide variety of scenarios where emphasis is placed on the wireless nodes’ battery life. READ MORE

  5. 9. Security in low power wireless networks : Evaluating and mitigating routing attacks in a reactive, on demand ad-hoc routing protocol

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Tony Fredriksson; Niklas Ljungberg; [2017]
    Keywords : IoT; Security; Ad-hoc Routing; RIME; Sinkhole; Selective Forwarding; Sybil; Intrusion Detection System;

    Abstract : Using low energy devices to communicate over the air presents many challenges to reach security as resources in the world of Internet Of Things (IoT) are limited. Any extra overhead of computing or radio transmissions that extra security might add affects cost of both increased computing time and energy consumption which are all scarce resources in IoT.
