  1. 1. IOT CONNECTIVITY WITH EDGE COMPUTING

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Maximilian Stiefel; [2018]
    Keywords : ;

    Abstract : 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. READ MORE
