Biometric based Security Solutions for MANET: A Review

Mobile ad hoc networks are self organizing, infrastructure-less, low power networks, design to deploy bandwidth-shared radio channel communicat ion and to work under vulnerable environ ment. Security is primary concern in MANETs and in order to achieve high security (confidentiality, integrity, authentication, availability and non repudiation), several techniques have been exp lored in which b io metrics with cryptography or intrusion detection has gained a mo mentum in recent years. This paper critically reviews and investigates the present biometric based security models works for MANETs, and along with security challenges and direction of further research are proposed.
