+Initially the term was coined to describe \gls{RFID} devices and the
+communication between them. However, currently the term \gls{IoT} encompasses
+all small devices that communicate with each other and the world. These devices
+often contain sensors, \gls{GNSS}\footnote{e.g.\ the American \gls{GPS} or
+the Russian \gls{GLONASS}} and actuators\cite{da_xu_internet_2014}. With these
+new technologies information can be tracked very accurately using very little
+power and bandwidth. Moreover, \gls{IoT} technology is coming into people's
+homes, clothes and in healthcare\cite{riazul_islam_internet_2015}. For example,
+for a few euros a consumer ready fitness tracker watch can be bought that
+tracks heartbeat and respiration levels.
