Security Related Issues in Mobile Ad Hoc Networks

Mobile ad hoc networks (MANETs) are one of the fastest growing areas of research. They are an attractive technology for several applications, such as rescue and planned operations, due to the flexibility provided by dynamic infrastructure. Furthermore, many conservative security solutions used for wired networks are ineffective and inefficient for the highly dynamic and resource- constrained environments. We introduce the security issues specific to MANETs and present a detailed classification of the attackers against these complex distributed systems. Then we discuss various proactive and reactive solutions proposed for MANETs. It then addresses the possible solution to protect the security mechanism, which involves availability, integrity, authentication and nonrepudiation. In this paper, we discuss about security issues and their solutions in the mobile ad hoc network. Owe to the vulnerable nature of the mobile ad hoc network, there are several security threats that disturb the development of it. We first analyse the main vulnerabilities in the mobile ad hoc networks, which have made it much easily to suffer from attacks than traditional wired network. Finally we survey the current security solutions for the mobile ad hoc network.
