Random linear network coding based physical layer security for relay‐aided device‐to‐device communication

Physical Layer Network Coding

A main distinguishing feature of a wireless network compared with a wired network is its broadcast nature, in which the signal transmitted by a node may reach several other nodes, and a node may receive signals from several other nodes simultaneously. Rather than a blessing, this feature is treated more as an interference-inducing nuisance in most wireless networks today (e.g., IEEE 802.11). Th...

Exploring the Security Capabilities of Physical Layer Network Coding

In wireless networks, the bandwidth is considered one of the most scarce and valuable resources. The physical layer network coding (PNC) technique encourages strategically picked senders to interfere so that the destination nodes can leverage the network level information to recover the signals. PNC can yield higher capacity than network layer network coding when applied to wireless networks. H...

NCSA: A New Protocol for Random Multiple Access Based on Physical Layer Network Coding

This paper introduces a random multiple access method for satellite communications, named Network Codingbased Slotted Aloha (NCSA). The goal is to improve diversity of data bursts on a slotted-ALOHA-like channel thanks to error correcting codes and Physical-layer Network Coding (PNC). This scheme can be considered as a generalization of the Contention Resolution Diversity Slotted Aloha (CRDSA) ...

Noncoherent Detection for Physical-Layer Network Coding

This paper investigates noncoherent detection in a two-way relay channel operated with physical layer network coding (PNC), assuming FSK modulation and short-packet transmissions. For noncoherent detection, the detector has access to the magnitude but not the phase of the received signal. For conventional communication in which a receiver receives the signal from a transmitter only, the phase d...
