MAC controller for Wireless Sensor Network on IEEE 802.15.4 standard

This paper presented an architecture of IEEE 802.15.4 standard-based MAC controller containing improved CSMA/CA mechanism, hardware security mechanism, efficient frame processing, ACK mechanism etc. The design of MAC controller individual module and detailed structure is completed optimal. Module level of this MAC controller is simulated after the RTL level design, and is verified via FPGA. The hardware implementation of all the MAC functions mentioned above provides strong support for the MAC protocols. The experimental results show that the average clock speed can be up to 64MHz.
