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. Simulation results shows the demonstration of Dynamic clustering approach have better system performance in terms of QoS performance metrics such as end to end delay, energy consumption, key delivery ratio and packet loss rate under varying network conditions.
