Wireless local area networks in the manufacturing industry

Based on the definition of IEEE 802.11 and the requirements of real-time control and monitoring, we introduce a new protocol-Prioritized CSMA/CA-for real-time wireless local area networking. For the first time, we propose and validate several new algorithms, a constant penalty, an estimated error order and a lag first order for dynamically scheduling the traffic of wireless networked control systems. All algorithms are compared via simulation and the results show that dynamic scheduling algorithms achieve better system performance on average than static scheduling algorithms, like fixed order polling
