Abstract

The emphasis for the use of wireless LAN in industry is on robustness, reliability and security. Almost any given single secruity mechanism (such as MAC filtering) alone may be easily overcome by attackers. However, proper configuration and implemetation of the maximum possible security mechanism must be used to form a multiple security layers, to provide the best possible wireless protection. The present paper deals with cross layer based miss detection ratio under variable rate for intrusion detection in WLAN. In cross layer based intrusions detection, the decision is based on the combine on weight value of two or more layer. So the decision is not based on single layer, it will reduce false positive rate. Two different layers, physical and MAC have been used in the present study and the results have been compared with existing technique.

Key words: Reciever signal strength (RSS), time taken for RTS-CTS handshake (TT), radio frequency (RF).
