Title: Biometric based Security Solutions for MANET: A Review

Section 1: INTRODUCTION
Description 1: Explain the concept of Mobile Ad hoc Networks (MANETs), including their features, application domains, and inherent security challenges.

Section 2: SECURITY CHALLENGES
Description 2: Detail the various security challenges specific to MANETs, such as bandwidth constraints, trust-based computing, dynamic routing and topology, resource constraints, distributed working approach, and insecure working environment.

Section 3: ATTACKS
Description 3: Discuss the types of attacks on MANETs, specifically active and passive attacks, and provide examples of each, such as dropping, modification, fabrication, timing attacks, eavesdropping, malicious behavior of nodes, session hijacking, repudiation attacks, Sybil attack, and wormhole attack. 

Section 4: BIOMETRICS
Description 4: Provide an overview of biometric technologies, their applications, strengths, weaknesses, and how biometric data can be used for continuous authentication in MANETs.

Section 5: CRYPTOGRAPHY
Description 5: Describe the role of cryptography in ensuring confidentiality and integrity within MANETs and explain the different types of cryptographic techniques used, such as symmetric and asymmetric key algorithms.

Section 6: INTRUSION DETECTION SYSTEM
Description 6: Describe intrusion detection systems (IDS), focusing on network-based and host-based IDS, and how they can be used to protect MANETs from malicious activities.

Section 7: LITERATURE SURVEY ON BIOMETRIC BASED SECURITY SOLUTIONS
Description 7: Include a detailed review of existing biometric-based security solutions, combining biometrics with cryptography and intrusion detection systems, and discuss the effectiveness and limitations of these solutions.

Section 8: CONCLUSIONS
Description 8: Summarize the main findings from the paper, discuss the viability of biometric-based security solutions for MANETs, and identify areas for future research.
