To Evaluate and Improve OLSR Protocol to detect and isolate Gray hole Attack in Mobile Ad-hoc Network

  Vikramjeet Singh,  Ranbir Singh

MANET is infrastructure less, decentralized multi hope network where the nodes are randomly to move in any direction, there each node works as a router and host to send packet to each other, there is no any requirement of fixed infrastructure. There are many security threats in MANET. Various types of attacks can be easily trigger in the network. So manet has a security issue. In this paper we have discussed about grayhole attack in OLSR protocol. Due to this attack network performances degrade. Therefore a novel technique has been proposed to detect and isolate gray hole attack in the network using monitoring nodes.
