It is hard to detect it because an attacker uses the side channel information to perform the attack [4]. trailer Security issues arise in many different areas including physical security, key management, routing and intrusion detection, many of which are vital to a functional MANET.

The existing physical layer security techniques can be classified into five major categories which are (i) theoretical secure capacity (ii) power (iii) code (iv)chan-nel (v) signal detection approaches. They claimed that their protocol not only prevents insider attack but it is also immune to several known security attacks. the data and retransmit it. In this paper the researchers work on the aspect of leadership at an educational institute as a means of enhancing the creativity and innovation of the employees. Jamming and eavesdropping are two primary attacks at the physical layer of a wireless network.
