  1. 1. Wireless electrocardiogram based on ultra-wideband communications

    University essay from Uppsala universitet/Signaler och System

    Author : Maria Toll; [2019]
    Keywords : UWB; ECG; EKG; ultra-wideband; electrocardiogram; ultra wideband; radio communication; Decawave; DW1000; IoT; internet of things; Android; IEEE 802.15.4-2011;

    Abstract : The goal for this master thesis is to develop a prototype that uses ultra-wideband (UWB) communications to wirelessly transfer electrocardiogram (ECG) data from an ECG measurement unit to an Android device (smartphone or similar) which is used to process and display the ECG signals. The prototype should consist of two hardware nodes; (1) Node one having a ECG measurement unit (an AD8232 single lead heart rate monitor), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE); and (2) Node two having an Android device (an Android smartphone), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE).

  2. 2. A comparison of the security in ZigBee and the IEEE 802.15.9 standard and an experimental analysis of communication over IEEE 802.15.4

    University essay from Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Institutionen för datavetenskap

    Author : Nicklas Silversved; Hampus Runesson; [2019]
    Keywords : IEEE 802.15.4; IEEE 802.15.9; ZigBee; security; key establishment; key management protocol;

    Abstract : The increasing number of IoT devices used in today’s society has led to a demand for better security in order to prevent attackers from gaining access to private information. The IoT brings a wide application scope and because of that there are a lot of ways to set up a secure network and manage keys in these kinds of networks. READ MORE

  4. 4. Evaluating the functionality of an Industrial Internet of Things system in the Fog

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

    Author : Mathias Granlund; Christoffer Hoppe; [2018]
    Keywords : IoT; IIoT; Fog; Cloud; Closed-loop control system; RPL; 6LoWPAN; Contiki-OS; Cooja; TmoteSky; IEEE 802.15.4; CoAP;

    Abstract : The Internet is one of the greatest innovations ever created by mankind, and it is a technical trend that has moved into industries to facilitate automation, supervision and management in the form of IoT devices. These devices are designed to be extremely lightweight and operate in low-power and lossy networks, and therefore run a low duty cycle and CPU-clock frequency to reserve battery life. READ MORE
