Industry is currently investigating the use of networked
wired and wireless technologies in monitoring, automation,and
control [1]. The primary benefit of wireless technology is
essentially the reduced installation cost, both financially and
in labor, as a considerable investment is made in the wiring
of factories. The use of wireless technology is not only
are placement of cables, the benefits go beyond that. With
wireless devices, increased flexibility is gained, as sensors can
be placed more freely in a plug-and-play fashion, even on
rotating machines. Cable failures are eliminated and wireless
communication is robust, as it can be done over several paths
in a mesh-net work. Finally, there are the opportunities for new
applications that are enabled by wireless control.
