An adhoc network is a decentralized type of wireless
network. It does not have any fixed infrastructure and the
nodes can communicate directly between each other [1]. It is
made up of multiple nodes connected by links. Security in
adhoc networks is a major problem since they are wireless and
unsecured in nature. [4].To provide security, the nodes must
share a secret key only to the authenticated neighbour nodes,
so that we can achieve the various security goals like
confidentiality, integrity, non repudiation, authentication, and
availability. The main advantage of adhoc network is its cheap
and easy construction.
