The threat of cyber intrusion is progressively high and harmful. Intrusion Detection Systems (IDS) provides the ability to identify security breaches in a system. A security breach will be taking any action based on the owner of the system believes unauthorized. Attacks in Wireless Networks (WNs) aim in limiting or even eliminating the ability of the network to perform its expected function. WNs are networks with limited resources and often deployed in uncontrollable environments that an intruder can easily access. WN attacks target specific network layer’s vulnerabilities but normally affect other layers as well. Network layer should be monitored and evaluated in order to detect possible malicious intervention. In this research, a general methodology of an anomaly-based Intrusion Detection System is proposed and evaluated the proposed system using routing layer attacks in Ad-hoc Distance Vector Routing (AODV) protocol and IDS is able to detect malicious activity and our solution delivered the packets to the receiver in a new route without discarding.
