  Devices with the ability to connect to the internet are growing in numbers
day by day thus creating the need for a new way of manag-ing the way the
produced traffic travels through data networks. Smart Cities, Vehicular Content
Networks, Healthcare and Virtual Reality Videos are a few examples that require
high volume data while maintaining low latency. Edge caching practices are a
prom-ising solution in such cases in order meet the requirements of low latency
in high volume traffic. This paper is a survey on four indic-ative areas, Smart
Cities, Vehicular Content Networks, Healthcare and Virtual Reality Videos that
make use of edge caching.
