Optimized Managed Mobile Adhoc Networks Using Intermittent Clusters

Abstract

We consider the problem of appropriate cluster head selection in wireless ad-hoc networks where it is necessary to provide robustness in the face of topological changes caused by node motion, node failure and node insertion/removal. The main contribution of our work is a new strategy for clustering a wireless AD HOC network and improvements in SWCA. Prior approaches didn’t implement any security aspects leading to a open manet architecture which is not feasible mission critical applications. So we propose a digital certificate based Key-Request(KREQ) optimization algorithm that is  void of latency factors required for rendering a certificate to support secure communications. Using these new messaging formats and combined with the above optimization algorithm we claim that node authentications and communications are secure with the possible usage of certificate schemes and the performance is highlighted through our extensive simulations.
