Security enhancement and certificate revocation in MANET using position and energy based monitoring

الملخص EN

Mobile Ad-hoc Network (MANET) has an advantage over their mobility and ease of deployment but it is vulnerable to various attacks to degrade the security in the network.

Using cluster based certificate revocation with combination of both voting and non-voting based mechanism, attacker’s certificate is revocated.

But this mechanism is vulnerable to the detection of false accusation in quicker time and attacks related to high energy consumption like stretch and carousel attack.

To overcome this issue and to enhance the security, Cluster based scheme along with position and energy based monitoring is proposed to revocate the certificate of the attacker node by the Cluster Authority (CA) node.

Guaranteed secure network services and low energy consumption of 9% and 13% is obtained after avoiding stretch and carousel attacks respectively.

It increases the Quality of Service (QoS) and reduces the packet loss in the network.
