  3. 17. IOT CONNECTIVITY WITH EDGE COMPUTING

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Maximilian Stiefel; [2018]
    Nyckelord :;

    Sammanfattning : Billions of Internet of Things (IoT) devices will be connected in the next decades. Most devices are for Massive Machine Type Communication (MMTC) applications. This requires the IoT infrastructure to be extremely efficient and scalable (like today’s Internet) to support more and more devices connected to the network over time. LÄS MER

  4. 18. Wireless electrocardiogram transmission based on ultra wideband radio

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Nyckelord :Ultra wideband; uwb; ekg; ecg; radio; decawave; communication system; IoT; internet of things; android; compare; bluetooth; wifi; IEEE 802.15.4-2011;

    Sammanfattning : Ultra wideband (UWB) communications has been a subject of much discussion over the last decade. The method of UWB has had a hard time to establish itself among other methods such as Bluetooth and WiFi but as internet of things (IoT) gains a foothold in our daily lives, UWB has presented some new application areas.

  5. 19. UWB-based wireless sensor network with medical application

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Joakim Lindström; [2018]
    Nyckelord :;

    Sammanfattning : This master thesis aims to develop a prototype of a wireless sensor network (WSN) using ultra wideband (UWB) radio and communication. The WSN consists of five sensor nodes and one sink which is connected to an Android smartphone. The smartphone acts as a sensor data management unit and has the ability to display sensor measurements. LÄS MER

  7. 20. Evaluation of Key Management Protocols and Their Implementations

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Erik Andersson; David Combler; [2018]
    Nyckelord :Key Management Protcol; Key Management; Evaluation; Comparison; IKEv2; HIPv2; PANA; 802.1X; Implementation; strongSwan; OpenHIP; openPANA; Open1X;

    Sammanfattning : When constructing a network system it is important to consider the attributes which define said system and how to best build around those attributes. In this report we’ve studied Key Management Protocols as well as 802.15.4 WPAN networks and how key managment is conducted in such networks. LÄS MER
