Security Issues in Mobile Ad-Hoc Networks

In this survey paper we have studied about different Mobile Adhoc networks in the infrastructure less wireless network. In a network the mobile nodes move rapidly from one node to the another. The application of MANET requires very good efficient group communication for the data transfer. The security constraints taking place in the MANET is very low when compared to the wired network. This survey paper is discussing not only the the different Mobile Ad-hoc networks, but also about the different attacks in the MANET layers. These attacks in the MANET layers are may be active or passive. The passive attacks does not alter by the attacker. The main focus of the active attacks is on the network layer protocols.
