Abstract

Nodes in MANET are powered by limited batteries and their lifetime is usually less as compared to other networks such as mobile ad hoc networks. In such kind of networks, the nodes must work for longer duration of time because the replacement of the batteries is very costly affair. Since these nodes communicate wirelessly with each other, these nodes are susceptible to various kinds of security attacks. While most of the attacks have the false intention of capturing the packets and information from the network, the malicious nodes tend to drop the packets being routed towards them. These packet dropping attacks result in loss of information while other attacks aim at consuming the resources of the 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. This special arrangement is in the form of certificate exchange. So that two or more persons who has authentic certificate can exchange data amongst themselves. 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.
