Review Paper on Security Issues in Mobile Adhoc Networks

Mobile Ad Hoc Networks (MANETs) have received drastically increasing interest, partly owing to the potential applicability of MANETs to myriad applications. The deployment of such networks, however, poses several challenging issues, due to the dynamic nature of the nodes, the arbitrary topology, the limited wireless range of nodes, and transmission errors. Since all the nodes in the network collaborate to forward the data, the wireless channel is prone to active and passive attacks by malicious nodes, such as Denial of Service (DoS), eavesdropping, spoofing, etc. Implementing security is therefore of prime importance in such network, 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. We focus on the findings and future works which may be interesting for the researchers However; in short, we can say that the complete security solution requires the prevention, detection and reaction mechanisms in MANET.
