Abstract. This paper describes a MPCS communication protocol developed to
solute the problem of different Programmable Controllers communication in
ubiquitous industrial environment. The MPCS protocol can overcome the dis-
advantages of MODBUS polling mechanism, and achieve higher throughput,
lower average message delay and less average message dropping rate in wire-
less communication. The experimental result of a wireless network in industrial
environment also is reported. It illustrates that the MPCS protocol can perform
well in industrial application.
Keywords: Wireless networks, Ubiquitous Computing, Programmable Control-
ler (PLC).
1 Introduction
Wireless networks have been under rapid development during recent years. Types of
technologies being developed to wireless personal area network for short range, point-
to multi-point communications, such as Bluetooth and ZigBee. [1] The application of
wireless technology for industrial communication and control systems has the poten-
tial to provide major benefits in terms of flexible installation and maintenance of field
devices and reduction in costs and problems due to wire cabling. [2]
Wireless communications from machine to machine greatly enhance automation of
an industrial system. Ubiquitous industrial environment is coming and allows the
engineers to acquire and control the real-time data of wireless networks of the factory
at anytime anywhere. [3]
A key issue currently limiting ubiquitous industrial environment development in-
volves compatibility among components in industrial environment from different
suppliers, generally referred to as interoperability. Full compatibility among compo-
nents would also provide end users with the flexibility to connect highly specialized,
high-end sensors with best-in-class wireless interface devices. [4]
Interoperability in ubiquitous industrial environment means wireless communica-
tion protocol and the protocol of monitoring and controlling industrial equipments are
interoperable. Interoperable wireless protocols are making or have appeared by some
international organizations and alliances, such as ISO, WINA, ZigBee, etc. Most
industrial equipments have their special monitoring and controlling protocols. PLC is
