Device To Device Communication

Device-to-Device (D2D) communication is used for cellular networks. D2d communication is the direct communication from one mobile station to other mobile station, without the involvement of the base station. By using the device to device communication lesser delay is possible. By using d2d communication along with 5G network improves the bit rate. 5G network provides the communication with more data rate and lesser delay. Security and privacy are very important for communication. In this paper security and privacy requirements of device to device communication and physical layer privacy solutions are discussed.

Physical Layer Secrecy

Wireless communication system limits the security and privacy because of its broad cast nature. Physical layer security gives secure correspondence and having legitimate user to effectively get secure data. Among the physical layer security techniques, an artificial fast fading (AFF) technique dtrait’s the received signal quality of eavesdroppers by causing pseudo fast fading to the transmitting signals. This is realized by multiplying the signals to be transmitted by random weights every symbol interval. However, the AFF technique often increases the power of the weighted signals. In such cases, the weighted signals must be normalized before transmission. This causes energy loss in the legitimate receiver. Therefore, we consider minimizing the norm of the weight vector to prevent the power of the weighted signals from being increased. In this, we propose and achieve Physical layer secrecy rate in MISO system using artificial fading plus information theory.
