Performance of Optimized Security Overhead Using Clustering Technique Based on Fuzzy Logic for Mobile ad hoc Network

Abstract MANET is an autonomous wireless network without any centralized authority, consisting of a dynamic topology with multi-hop scenario. Clustering provides authority within and makes the stable up to some extent. Security one most challenging aspects, directly proportional load overhead over network. The model being proposed uses cluster-based technique modified secure routing protocol, which minimizes network’s overhead, improving security performance. Two major factors are used as contribution level stability factor for choice cluster head, method re-selection head. node addition using authentication Modified Secure Routing Protocol increases Protocol, based on limited efficient use certificates encryption decryption packets, Hence, it more efficiency security.
