In this paper, we present and analyze utilizing generalized selection combining (GSC) scheme to enhance the physical layer (PHY) security of a wireless communication system consisting of a single antenna transmitter, a multi-antennas receiver and a multi-antennas eavesdropper. We consider a practical scenario where GSC scheme is applied to the receiver considering both the complexity and the energy...
With the rapid development of electronics and wireless communications technology, wireless sensor networks consisting of many wireless sensors can he used for various application fields such as military, chemical, business. Since most wireless sensor network applications have strict security requirements, security is a critical issue in wireless sensor networks. However, the new ZigBee has the security...
