Employing Game Theory and TDMA Protocol to Enhance Security and Manage Power Consumption in WSNs-based Cognitive Radio
The rapid development of wireless sensor networks (WSNs) is the significant
incentive to contribute in the vulnerable applications such as cognitive radio
(CR). This paper proposes a Stackelberg game approach to enhance the WSN-based
CR security against the spectrum sensing data falsification (SSDF) attack and
conserve the consequent lost power consumption. The attack aims to corrupt the
spectrum decision by imposing interference power to the delivered reports from
the sensor nodes (SNs) to the fusion center (FC) to make a protection level
below a specific threshold. The proposed model utilizes the intelligent
Stackelberg game features along with the matched filter (MF) to maximize the
number of protected reports sent by the SNs to the FC leading to accurate
decision of the spectrum status. Furthermore, the TDMA protocol is utilized to
resolve the complexity of employing MF for the spectrum detection to avoid the
collision between the delivered reports. The proposed model aims to enhance the
number of correctly received reports at the FC, and hence manage the lost
energy of reports retransmission due to the malicious attack effect. Moreover,
the model can conserve the lost power of the failure communication attempts due
to the SSDF attack impact. Simulation results indicate the improved performance
of the proposed protection model along with the MF over the six different
environments against the SSDF attack as compared to two defense schemes,
namely, random and equal weight defense strategies.Comment: 14 pages 13 figure
