DoS Attacks on IEEE 802.11 Wireless Networks and its Proposed Solutions

In recent times, wireless Local Area Network (WLAN) became very popular in approximately all enterprises, organizations and universities. It motivates to provide more security in WLAN, so many high level security protocols for IEEE 802.11 has been developed. E.g. WEP, WPA, WPA2. These protocols are unable to protect our WLAN from the DoS (Denial of Service) attacks. This paper shows how these attacks are launches, how to create threats in security and what will be the effect of these attacks on the WLAN. Paper also shows that how easily to do attack on the WLAN while so difficult to prevent the same and some solutions to prevent them also proposed.
