Security Issues in Mobile Ad Hoc Networks

In wired networks, there are lots of protections while communication occurs. In these networks, the intruders are pass through the firewalls and secured gateways for safe and secured communications. Moreover, the wired networks ensure the secured communications. But, in the case of wireless mobile ad hoc networks, the nodes are dynamic and the topology based and also needs more power consumptions. Because of mobility in wireless mobile adhoc networks, also there are lots of vulnerabilities when the attackers wish to collapse the partial or entire networks. Hence, there are lots of requirement for an understanding of the various problems associated with the wireless mobile networks. In this paper, the various vulnerabilities, attacks and security mechanisms are discussed for mobile ad hoc networks (MANETs) in detail.
