Abstract:
Most important parameters in Industrial Communication Networks arre packet delay and reliability. In this paper, packet delay and retransmission characterist ics of Multiple Input Multiple Output (MIMO)-enabled wireless industrial networks using a simple Spatial-Diversity (SD) scheme in physical layer has been analyzed. Result s show that due to the low Signal to Noise Ratio (SNR) in factory environment, simple modulation schemes with lower spectral efficiency have better delay performance and the default retry-limit parameter of 7 will satisfy the reliability of about 100%. Other wise, the delay will e highly sensitive to SNR, packet payload, number of competing n odes and other parameters.
