The following are the security
threat in adhoc network.
1. Limited computational
capabilities : the nodes in the mobile adhoc network are modular,
independent and will have limited computational capability. It becomes a source
of vulnerability when they handle public key cryptography.
2. Limited power supply : since
nodes have limited power supply attacker can exhaust batteries by giving
excessive computations to be carried out.
3. Challenging key management
: the key management becomes extremely difficult as the mobile devices will
be under movement.
