| Abstract(in English) | Recently, some power allocation methods for L-link MIMO system are proposed. However, these schemes do not consider security. Wireless communications are eavesdropped easily compared with wired communications. When a transmitter sends information to its intended receiver, we afraid the eavesdropping by other receivers In this report, we propose power allocation considering secrecy capacity based on game theory in L-link MIMO system to guarantee its security. The security level of each link is determined by the secrecy capacity. In the proposed scheme, power is allocated so that the secrecy capacity to another link becomes larger than 0. Therefore, information is not eavesdropped by the receiver of another link and information can be transmitted to its intended receiver securely. We show that the proposed scheme improves security compared with the conventional scheme that is power allocation based on game theory considering capacity. |
