Optimization on channel assignment based on stave principle in star-topology WirelessHART networks

With rapid development of wireless sensor networks, especially WirelssHART networks, channel assignment in physical layer has been becoming an obstacle for data transmission with increasing amount of various field devices. This paper is mainly written to describe, in star-topology WirelessHART networks, the optimization on channel assignment based on stave principle, which is analogous to a mathematical graph of pitch with respect to time for music notes recording. And the optimization algorithm verification, which adopts software simulation verification and measurement, is then proposed to validate the feasibility and operability of this kind of optimization algorithm. The tasks fulfilled in this paper, also, are related to an ongoing WirelessHART project cooperated with GE, an abbreviation of General Electric Company.
