Abstract: A mobile ad hoc network is a self-configured wireless network in which any mobile node can freely access the network at any time without the need of any fixed infrastructures. Due to high dynamic characteristics, these types of networks are easily prone to various security attacks. There are various mechanisms which provide secure communication i.e., certificate revocation. In this paper, the main challenge of certificate revocation (i.e., to revoke the certificates of the intruders inorder to permanently exclude them from the network activities) is accomplished by adopting CCRVC scheme that also deals with false accusations apart from outperforming the other techniques in case of revoking the intruders certificates. Also this scheme enhances the reliability as well as accuracy as it can vindicate the warned nodes promptly based on the threshold based mechanism. Energy of the nodes must be utilized in an effective manner inorder to secure the network for longer durations as the mobile nodes operate on their batteries. Further, a new technique was proposed, to utilize the energy of the nodes effectively by switching the CHs in a timely manner (since the CHs are likely to lose more energy). Experimental results evaluated by using NS-2 show that the proposed scheme EECCRVC is efficient enough in providing secure communications along with effective energy utilization in mobile ad hoc networks.
