Abstract
Cyber attacks are becoming a major challenge in today’s connected
environment. More personal devices are connected and operated in a wireless
environment. Securing the wheless network needs better solutions in terms of
its quality of service. There are many methods available in the literature to
handle cyber attacks. Moving target defense mechanism is one of the
upcoming and promising mechanisms to handle cyber attacks. Decoys, one of
few moving target defense mechanism that is rarely explored. Time triggered
approach and Event triggered approach are the two current approaches that
dynamically help to secure the data in decoys defense type. The very
important aspect to be noted here is that most of the methods provide security
with compromised Quality of Service. To overcome this, while handling cyber
attacks, an integrated time and event triggered method with AntNet protocol is
proposed. The key feature of the proposed method is to defend the wireless
networks against cyber attacks and to ensure Quality of Service (QoS) while
handling the attacks. The effectiveness of this system is validated by
conducting various experiments. The proposed method can identify the
unauthorised user i.e. attacks in a precise way. The performance of the
proposed method is evaluated based on the metrics like end to end delay,
thi'oughput, routing overheads, packet delivery ratio, latency and energy
consumption. The proposed methodology is tested in a simulated environment
with Linux Fedora and Network Simulator NS2 version ns-allinone-2.35.
