In this study, we have focused on wireless communication networks which can easily construct a network by using the relay function of the wireless station. With relay stations, a physical layer network coding (PLNC) enables efficient transmission and suppression of information leakage at relay stations. However, when the two stations simultaneously access the relay station, the relay station may exploit the information from the received signal owing to the much difference of the received signal power between two stations,where it is capture effect.
Each wireless station will carry out transmission power control based on channel state information (CSI) notified from the relay station for supporting capture effect. On the other hand, the relay station may camouflage the CSI for exploitings the information so as to dominate eavesdropping.
Authors have carried out evaluation from the viewpoint of the two-objective optimization problem because there are two objective quantities in this model. In this paper, we generated a payment matrices for two objective quantities with different characteristics secure capacity and exploitation capacity, and evaluated the security of the system using game-theoretic techniques under conditions where they were independent and non-cooperative. |
