Abstract: In Mobile Adhoc network, the secure key management and energy efficient route discovery is difficult and challenging due to the nature of dynamic infrastructure less network. In this study we propose a new secure and energy efficient clustering scheme to form zone based secret key management clustering. This is used to provide secure communication in Adhoc networks with quality of service. The mobile nodes lose their maximum energy by discovering the efficient route to reach its destination. We propose an efficient mechanism for key update, key revocation schemes and key management for Mobile Adhoc networks using Mobile Adhoc Energy Efficient Secure Cluster scheme (MAEESC). The main objective of this study is to improve energy and reduce overhead in wireless network with secure manner.
