Secure Routing Protocols for Mobile Ad-Hoc Network (MANETs) –A Review

Abstract: Mobile Ad-hoc network (MANET) is a self configuring, multi hop wireless network. Security in mobile ADHOC network is a big challenge because there is no centralized authority which can supervise the individual nodes operating in the network. The attacks can come from inside the network and also from the outside. This article surveys classifies the secure routing protocol in MANET, and also discussing presently proposed method of mitigating those attack. In the routing protocol of the MANET while forwarding data packets to other nodes, some intermediate node extract useful information packets and can't forward the packet to the next node. Some node may modify the content of packets during the data transmission session. So that any one node can manipulate the original data.
