In this paper, the authors comprehends an impending accost of intensifying Biometric Stationed Authentication Protocol (BSAP) bestowing meta-heuristic genetic algorithm for securing MANET. Biometric authentication using fingerprint, facial, iris scan, voice recognition etc. have gain a lot of importance in recent years to provide security in MANET. Biometrics is more advantageous and secure as compared to prevailing data security techniques like password or token mechanisms. A higher level of security is achieved in their impending approach using genetic algorithm to overcome the security and privacy concerns that exist in biometric technology.
