Journal ArticleDOI
Edge computing in smart health care systems: Review, challenges, and research directions
TL;DR: This paper aims first to survey the current and emerging edge computing architectures and techniques for health care applications, as well as to identify requirements and challenges of devices for various use cases.
Proceedings ArticleDOI
Enabling proactive self-healing by data mining network failure logs
TL;DR: This paper investigates spatio-temporal trends in a large NFL database of a nationwide broadband operator and extracts trends that can enable the operator to proactively tackle similar faults in future and improve QoE and recovery times and minimize operational costs, thereby paving the way towards proactive self-healing.
Journal ArticleDOI
User-Centric Cloud RAN: An Analytical Framework for Optimizing Area Spectral and Energy Efficiency
TL;DR: A statistical framework to quantify the area spectral efficiency (ASE) and the energy efficiency (EE) performance of a user-centric cloud based radio access network (UC-RAN) downlink and shows that the tradeoff between the ASE and the EE of UC-Ran manifests itself in terms of cluster radius selection.
Proceedings ArticleDOI
What user-cell association algorithms will perform best in mmWave massive MIMO ultra-dense HetNets?
TL;DR: This paper evaluates the performance of four user-cell association algorithms for massive MIMO deployment in a two-tier network under two different deployment scenarios and proposes a modified utility function that takes into account the effect of large bandwidth at mmWave bands.
