Packet Retransmission and Delay Assessment of Spatial Diversity- Enabled Reliable Wireless Industrial Networks 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.
