Immunization against Energy Draining Attack in Wireless Adhoc Network

In wireless ad-hoc network, each of the nodes has a wireless interface and communicates with each other via either infrared or radio. Laptop computers and personal digital assistants can communicate directly with each other. MANET is one Example. MANET is the new research technology which enables users to communicate without any physical infrastructure and also regardless of their geographical location. Some weaknesses in MANET are limited bandwidth, computational power, battery power and security.Due to nodes in ad hoc networks have very limited energy resources as they are battery powered and it is impossible to replace the battery or recharge it, we have to take care about the energy management. For this purpose we suggest one method that immunize against energy draining attack. In Energy draining attack, one of the node in the network work as victim or compromised node and can create some malicious effect such as loop creation, path stretch or unnecessary packet send. So due to this attack energy of the node is wasted. To reduce this effect we propose a method which uses AOMDV protocol for routing in MANET. This method identify this victim node and stop them to work for some time, so effect of energy draining attack will be reduced. AOMDV is the Extension of AODV which has some advantages compare to AODV such as 25% reductions in routing load and provide multiple loop free and link disjoint paths.
