The project named Intrusion Detection System for MAC Layer projects main idea is to prevent the network resources from illegal penetration and to provide efficient communication.

In wireless network there are many cases where packet loss or hacking packets had become a common problem which creates a reason for re checking implemented protocols in distributed systems. This paper will explain how different protocols in a network layer are affected because of misbehavior of nodes and MAC layer. In order to analyze the problem more accurately we will look after performances at each node and MAC layer using frame work and provide a optimal rule to for dealing in worst case attack in the MAC layer.
