2 Theoretical Considerations
2.1 WirelessHART
WirelessHART is a wireless sensor networking technology based on the Highway Addressable Remote
Transducer Protocol (HART). It is essentially the only released standard for wireless communication in
the process industry (De Biasi, Snickars, Landernäs, & Isaksson, 2008), and it is the first open
standard specifically designed for process control (Song, Han, & Mok, 2008). It was officially released
in September 2007. The structure of WirelessHART is depicted in Figure 2.1.
