A Review on Secure Routing Protocols in MANET

Abstract

Mobile Ad hoc network (MANET) is a collection of self configuring, multi-hop wireless network. Due to the mobility and dynamic nature of MANET, network is not secure. MANET is more vulnerable to different types of attacks and security threats because of its characteristics. A routing protocol in a mobile Ad hoc network should be secure against both inside and outside attackers. Most of the routing protocols in MANETs assume that all the nodes in a network will cooperate to each other while forwarding data packets to other nodes. But intermediate nodes may cause several problems like it can deny to forward the packet, can also extract useful information from the packet or may modify the content of packet. Such nodes are referred as malicious nodes. An Improvised Secure routing approach should be used to address these issues in MANET by applying suitable cryptography or encryption techniques which can prevent outside attackers. By applying intrusion detection system (IDS), internal attackers can be prevented. In this paper various previously used routing protocols are discussed. Analysis is done by considering various previously used mechanisms used by those protocols and aim is to find out one new authentication based approach for secure routing.
