The security of data becomes more important with the increased use of commercial

applications over wireless network environments. We presented an approach to handle various attacks

for wireless networks. There were several problems of security in wireless networks due to intruders

and different type of attacks such as Node Isolation, Route Disruption and Resource Consumption.

There were better methods and intruder handling procedures available for fixed networks but it was

difficult to analyze attacks in the mobile adhoc environments. The reason was due high mobility of

network nodes and lack of fixed infrastructure. Normally, attacks by an intruder cause unauthorized

use of the wireless network so that the whole network will be suffered from packet losses and reduced

throughput. So, we have performed a study on various issues of threats for Mobile Adhoc Networks

and presented an approach to handle such threats efficiently. The main principle was to use my-AODV

agent to introduce various attacks on existing AODV MANET routing protocol.
