Dynamic Clustering for QoS Based Secure Multicast Key Distribution in Mobile Ad Hoc Networks
Many emerging applications in mobile ad hoc networks involve group-oriented communication. Multicast is an efficient way of supporting group oriented applications, mainly in mobile environment with limited bandwidth and limited power. For using such applications in an adversarial environment as military, it is necessary to provide secure multicast communication. Key management is the fundamental challenge in designing secure multicast communications. Multicast key distribution has to overcome the challenging element of "1 affects n" phenomenon. To overcome this problem, multicast group clustering is the best solution. This paper proposes an efficient dynamic clustering approach for QoS based secure multicast key distribution in mobile ad hoc networks.
