  Recent advancements in technology now allow for the generation of massive
quantities of data. There is a growing need to transmit this data faster and
more securely such that it cannot be accessed by malicious individuals. Edge
computing has emerged in previous research as a method capable of improving
data transmission times and security before the data ends up in the cloud. Edge
computing has an impressive transmission speed based on fifth generation (5G)
communication which transmits data with low latency and high bandwidth. While
edge computing is sufficient to extract important features from the raw data to
prevent large amounts of data requiring excessive bandwidth to be transmitted,
cloud computing is used for the computational processes required for developing
algorithms and modeling the data. Edge computing also improves the quality of
the user experience by saving time and integrating quality of life (QoL)
features. QoL features are important for the healthcare sector by helping to
provide real-time feedback of data produced by healthcare devices back to
patients for a faster recovery. Edge computing has better energy efficiency,
can reduce the electricity cost, and in turn help people reduce their living
expenses. This paper will take a detailed look into edge computing applications
around Internet of Things (IoT) devices, smart city infrastructure, and
benefits to healthcare.
