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.
