System characterization of a cooperative transmission system approach to industrial wireless communication

Cooperative transmission system is proposed approach to wireless communication for industrial use. This system is suitable for a factory channel environment, because it can prevent packet delay resulting from long term shadowing with maintaining low power consumption. In this paper, several simulations are made to investigate the packet delay and power consumption properties. They have been carried out based on joint channel model of Rician fading and shadowing attenuation, and a novel evaluation algorithm which calculates the mean packet transmission time and the mean gross transmission energy to assess packet delay and power consumption. Results shows cooperative transmission system maintains low packet transmission time and gross transmission energy even for lower reduced transmission powers. It indicates that cooperative transmission system can reduce the transmission power while maintaining the packet transmission time.
