  1. 1. Erlang as an alternative to a non-functional language for communication in a faulttolerant IoT sensor network

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Jimmy Holdö; [2020-02-17]
    Keywords : Internet of Things; Wireless Sensor Network; Erlang; IEEE 802.15.4; ZigBee; Network topology;

    Abstract : This thesis compares a C++ prototype and an Erlang prototype for an Internet ofThings application. Internet of Things applications are difficult to program becausethey consist of a distributed environment of heterogeneous devices, where each devicecan have limited resources and connectivity technologies.

  2. 2. 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).

  3. 3. FPGA Co-Processing in Software-Defined Radios

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

    Author : Leon Fernandez; [2019]
    Keywords : Internet of Things; Software-Defined Radio; USRP; GNU Radio; IEEE 802.15.4; Sakernas Internet; Mjukvarudefinierad Radio; USRP; GNU Radio; IEEE 802.15.4;

    Abstract : The Internet of Things holds great promises for the future. In the smart cities of tomorrow, wireless connectivity of everyday objects is deemed essential in ensuring efficient and sustainable use of vital, yet limited resources such as water, electricity and food. However, radio communication at the required scale does not come easily. READ MORE

  4. 4. Virtualizing LoRa baseband functionalities to the Edge

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

    Author : Patrik Vijayendra Walvekar; [2019]
    Keywords : ;

    Abstract : Traditional network architecture design of Low Power Wide Area Networks (LPWAN) suffer from their inability to dynamically scale resources based on the incoming traffic and involve manual procedures for capacity upgrades. There is a need to develop a cloud-native architecture where the gateway hardware performs signal detection while baseband processing is virtualized in the Edge, provisioning for dynamic scaling of resources.

  5. 5. 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
