Abstract: This Paper is to prevent node isolation attack by reducing the severity of DOS (Denial of Service) attacks in Mobile Ad- Hoc Networks (MANET) which is using Optimized Link State Routing (OLSR) Protocol for packet transmission. The resulting protocols are more vulnerable to different kinds of attacks. Different solutions have been proposed for different types of attacks, however these solutions often Compromise routing efficiency or network overload. One of the major DOS attack against the Optimized Link State Routing protocol (OLSR) known as the node isolation attack. It occurs when topological knowledge of the network is exploited by an attacker and who is able to remove the victim from the rest of the network and subsequently deny communication services to the victim. In this project work, I have suggested a novel solution to reduce the severity of OLSR protocol from node isolation attack by using the same technique used by the attack itself. The proposed technique prevents more than 95 percent of attacks. The overhead required decreases as the network size increases until it is non-discernable.
