Possible Solutions of Different Security Issues and Challenges in Mobile Ad-Hoc Networks (MANETs)

Abstract-Today, the rising concern for flexible infrastructure services is a call for advanced researches in the emergence of 'Mobile Ad hoc Network'. It is a key technology that supports various ultramodern applications. Security is the important issue in every network. The security of MANET is important challenge due to its unmonitored deployment nature and its inherent resources limitation. Mobile Ad hoc Network is used in very sensitive fields such as rescue operations, home and enterprise network, education, military and airports. Therefore the addressing of security issues of network is most challenging task. Because of restricted possessions of mobile stations, the MANET security is more difficult to implement as compared to other traditional networks. Today huge research is going on in the field of security. Various techniques are now deployed to resolve the security issues. This paper provides a survey of security issues in this dynamic field such as denial of service attack, active and passive attacks, spoofing, eavesdropping, black hole attack, worm hole attack and rushing attack etc. This paper also presents a comprehensive survey of possible latest solutions available e.g. AODV (Ad hoc on demand distance vector), HMTI, Intrusion detection system, Fellowship etc
