A low-latency medium access control protocol for industrial wireless LAN applications

In this paper, a high-reliability and ultra-low-latency wireless MAC protocol for industry automation applications is introduced. The proposed MAC protocol supports the flexibility, mobility and scalability of the wireless industrial LAN, approaching the data throughput and latency performance of the recent wired industrial LAN. We demonstrate the MAC performance as function of several network parameters (number of nodes, data traffic downlink and uplink, data rate of the underlying physical layer, etc.), based on network simulations.
