“…In this case, we do not have to expect performance bottlenecks as in software solutions. On the other hand, the flexibility and extendibility of the hardware implementation will be restricted [19] [20].…”

In this paper, a novel Medium Access Control (MAC) protocol for industrial Wireless Local Area Networks (WLANs) is proposed and studied. The main challenge in industry automation systems is the ultra-low network latency with a target upper bound in the order of 1 ms while maintaining high network reliability and availability. The novelty of the proposed wireless MAC protocol resides in its similar latency performance as its counterpart in wired industrial LAN. First, the functional design of the MAC protocol is introduced. Then its performance results gained from hardware implementation (SystemC and VHDL) on an FPGA platform are presented. Finally, a real-time communication module which achieves the ultra-low latency required in industrial automation is described.

In this paper we are investigating the performance of a 802.11a compliant MAC protocol used in MIMAX (MImo for MAXimum reliability and performance) system. The protocol is developed in SDL (Specification and Description Language) and evaluated on a hardware platform. The evaluation results are later used to commit hardware/software partitioning of the protocol. The paper also describes testing setup used to investigate performance of the complete MIMAX system. It gives the measurement results and comparison to traditional 802.11a SISO implementation.

“…In the proposed methodology, first, the unified code for network simulation and system implementation is developed in C/C++ even though it can be generated from the specification and description language (SDL) because it is not an optimized code and does not reflect the system architecture [9][10][11]. The code includes every function of the MAC protocol described in this paper, including the functions to be implemented to hardware, as well as specialized functions for network simulation and system implementation.…”

Abstract-This paper proposes a unified medium access control (MAC) design methodology and presents the implementation of the IEEE 802.11ac down-link multi-user multi-input and multi-output wireless local area network MAC using the proposed design methodology. The proposed methodology employs unified code for both network simulation and system implementation. Because the unified code closely relates these two processes, the performance of the implemented MAC system can be estimated before implementation. The MAC architecture for an access point implemented using the proposed design methodology is verified on an ARM-based platform, and it is applied to a 65 nm CMOS library.Index Terms-WLAN, IEEE 802.11ac, MAC, MU-MIMO, unified design methodology
