Abstract: 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.
