Reliable and prioritized communication using polarization diversity for industrial Internet of Things

Abstract

Industrial Internet of Things (IIoT) requires superior reliability from underlying communication technology that consumer wireless technologies often fail to meet. New physical layer techniques have been proposed to enhance the performance of wireless monitoring and control networks to address this challenge. Utilizing polarization diversity techniques through Rotating Polarization Waves (RPW) have been recently proposed to improve the coverage and reliability of IIoT network. In industrial environments that have large metallic scatterers, RPW can improve the coverage and reliability as compared to fixed polarization radio waves. However, suitable multiple access protocol to utilize the polarization diversity is a subject of ongoing research. In this paper, novel medium access techniques to improve the reliability and support priority in the RPW wireless communication have been described. Also, an overview of medium access (MAC) protocol and analytical model to support above functions is provided.
