VHDL Modeling of the CSMA/CA

The wireless communication is highly deployed due to its convenience of mobility. The wireless local area network, WLAN is dominated by IEEE802.11 standard. All the new notebooks are equipped with the IEEE802.11 b WLAN. It becomes one of the main focuses of the WLAN research. Most of the researches are simulation based due to high cost required for the hardware implementation. The IEEE802.11b standard contains two major operations, the Distribution Coordination Function (DCF) and Point Coordination Function (PCF). The main core of the IEEE802.11b, the CSMA/CA and the IEEE802.11b Physical and MAC are modeled in this paper using VHDL.
