Implementation of Internet access control with FPGA for wireless LAN

This paper proposes an architecture and design of access control unit to implement Internet access control for wireless LAN, which integrates both hardware and software applications in a system on chip (SoC). Particular scheduling tasks such as registration and dynamic bandwidth allocation (DBA) are performed on an embedded Linux platform, while most control operations, including encryption, authentication, classification, and arbitration are implemented with field programmable gate array (FPGA) using hardware description language (HDL). Simulation results show that the proposed design functions properly in a relatively low cost FPGA.
