Analysis and Prevention of Security Issues in Manets

Security is a paramount concern in mobile ad hoc network (MANET) because of its intrinsic vulnerabilities. These vulnerabilities are nature of MANET structure that cannot be removed. As a result, attacks with malicious intent have been and will be devised to exploit these vulnerabilities and to disturb MANET operations. In this paper, we analyze the security problems in MANET, security threats and present a few detection and prevention directions. As MANET is quickly spreading for the property of its capability in forming temporary network without the aid of any established infrastructure or centralized administration, security challenges has become a primary concern to provide secure communication.
