A REVIEW PAPER ON SECURITY IN MOBILE ADHOC NETWORK
Anuj Mehta · 2017
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 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. We present a survey of the main types of routing protocols and some security threats and various detection scheme against attack.. This paper also classifies several common attacks against the ad-hoc networks routing protocols based upon the techniques that could be used by attackers to exploit routing messages.
