The security of data becomes more important with the increased use of commercial applications over wireless network environments. The authors 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.
