Predictive preemptive certificate transfer in Cluster-Based Certificate Chain

Sofiane Boukli-Hacene, Abdelkader Ouali, Asmaa Bassou


Mobile ad hoc networks are a set of nodes that cooperate and communicate wirelessly. This kind of networks in easy to deploy because there is no need of any pre-existing infrastructure. Security in Manets is a very important issue and it is hard to use conventional security techniques. Many approaches have been proposed to secure communication in Manets; most of them are based of public-key certifications which create a multitude of trust communication model.

In this paper, we propose an amelioration of a distributed certificate chain that relies on the cluster based routing protocol. In our scheme, after forming clusters, the cluster-head node issue certificates for other nodes within its cluster. When a member node want migrates to an adjacent cluster, the cluster-head sends the node’s certificate to surrounding cluster-heads via gateway nodes. The protocol was doted by a preemptive predictive module to predict migration intention of member nodes. This approach has been evaluated by detailed simulation study. Simulation results show that this approach is scalable and generate lower certification overhead.
