In a wireless network system the security is a main concern for a user. It is basically suffering from mainly two security attacks virus attack and intruders. Intruder does not only mean it want to hack the private information over the network, it also includes using a node bandwidth and increasing the delay of service for other host over the network. This paper is basically based on such type of attack. This paper reviews the comparison of different intrusion detection system. On the behalf of the reviewed work they proposed a new network intrusion system that will mainly detect the most prominent attack of wireless network i.e. DoS Attack.
