  1. 1. Internet of things and implementation of local wireless sensor network

    University essay from

    Author : Anthon Jonsson; [2019]
    Keywords : ;

    Abstract : This master’s thesis covers the research and development of a local wireless sensor network with capabilities for IoT (internet of things) applications and with the ability to monitor and automatically control a watering system with soil humidity as input. The goal with this thesis was to develop a system where the wireless communication within the local network is suited for low power and lossy networks (LLN). READ MORE

  4. 4. 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; 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.
