Physical Layer Security Using Two-Path Successive Relaying
Relaying is one of the useful techniques to enhance wireless physical-layer security. Existing literature shows that employing full-duplex relay instead of conventional half-duplex relay improves secrecy capacity and secrecy outage probability, but this is at the price of sophisticated implementation. As an alternative, two-path successive relaying has been proposed to emulate operation of full...
متن کاملOn Constellations for Physical Layer Network Coded Two-Way Relaying
Modulation schemes for two-way bidirectional relay network employing two phases: Multiple access (MA) phase and Broadcast (BC) phase and using physical layer network coding are currently studied intensively. Recently, adaptive modulation schemes using Latin Squares to obtain network coding maps with the denoise and forward protocol have been reported with good end-to-end performance. These sche...
متن کاملPerformance of Two-path Successive Relaying in the Presence of Inter-relay Interference
Half-duplex constraint refers to the inability of a radio to transmit and receive signals simultaneously due to the hardware limitation. In cooperative communication, half duplex constraint requires orthogonal time or frequency channel use between source transmission phase and relay transmission phase. This limits the spectral efficiency of conventional relaying to half of the performance of di...
متن کاملPhysical Layer Security Issues
Conventional wired networks are subject to being tapped by a variety of means, whether copper or fiber connections are used. In addition, methods of network snooping exist that make such eavesdropping minimally invasive, but no less significant. Wireless networking has additional characteristics that also decrease physical network security. As new technologies emerge, the potential for loss of ...
متن کاملWireless Physical Layer Security
Security in wireless networks has traditionally been considered to be an issue to be addressed separately from the physical radio transmission aspects of wireless systems. However, with the emergence of new networking architectures that are not amenable to traditional methods of secure communication such as data encryption, there has been an increase in interest in the potential of the physical...
