Adaptive Backbone and Link Correlation based Data Transmission Schemes for Wireless Sensor Networks
Masteroppgave informasjons- og kommunikasjonsteknologi - Universitetet i Agder, 2015 One of the main challenges faced by modern wireless sensor networks (WSN) is rapid energy depletion of individual sensor nodes. In many applications, sensor nodes are deployed in outdoor environments and it is difficult to replace or recharge node batteries. Depending on network topology and the transmission schemes implemented, certain nodes could have higher energy consumption compared with other nodes. In highly unbalanced load distributions this could lead to early total energy depletion of a critical node in the topology resulting in what is known as an energy hole in the network. Considering these fac…
Enabling mMTC and URLLC in 5G : Initial Access, Traffic Prediction, and User Availability
Paper II is not published yet. The 5th generation (5G) mobile communication networks focus on three main technology pillars as enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine type communications (mMTC). Among them, URLLC and mMTC introduce many novel challenging tasks for system and protocol design. This is a result of the stringent service requirements associated with URLLC and the massive number of devices that constitute mMTC. In this dissertation, we investigate three topics towards enabling mMTC and URLLC in 5G networks as stated below. The first topic which is the main focus of this dissertation lies in proposing initial acc…
