Abstract

MANET is the mobile ad-hoc network. It is infrastructure less network. There is no central controller which can control the network performance and secure the network from various kinds of attacks. There requires the special arrangement in the protocol so that the attacker node can be identified and removed. Dynamic anomaly detection using cross layer security in MANET for GrayHole Attack is the working taken place in Link layer. It is the layer in which all the data will be send. Every request will be send in network layer. Relay nodes will forward the route requests in the network layer and receives the route replay in the data link layer. Any attacker node will work to destroy these layer. They will send the false route request and overload the node buffer by sending the false route request. It is the special arrangement where any path which has more packet drop rate will be considered as the path having attacker node. Any new path which has those attacker nodes in the intermediate list will be avoided. So that network performance can be avoided to be downgraded. In proposed technique all the performance parameters like throughput, end to end delay, success rate and packet Delivery ratio has shown the improvement.
