Link Selection for Secure Cooperative Networks with Buffer-Aided Relaying

This paper investigates the secure communication in a two-hop cooperative wireless network, where a bufferaided relay is utilized to forward data from the source to destination, and a passive eavesdropper attempts to intercept data transmission from both the source and relay. Depending on the availability of instantaneous channel state information of the source, two cases of transmission mechan...

Battery-Aware Relay Selection for Energy Harvesting Cooperative Networks

The use of energy harvesting (EH) nodes as cooperative relays is an emerging solution for enabling green wireless systems. In this paper, we consider multiple EH relay nodes harvesting energy from the radio frequency (RF) signal received from the source and use that harvested energy to forward the source information to the destination. Unlike conventional relays with fixed power supplies, EH re...

Buffer-Aided Relaying in Cooperative Networks

Traditional half-duplex relaying schemes partition the packet transmission slot into two phases, where the SourceRelay link transmission is in the first phase, and the RelayDestination link transmission occurs in the second phase. As a result, the relay that received the source signal is the same as the one that is subsequently forwarding the signal towards the destination. However, these relay...

Virtual full-duplex buffer-aided relaying - Relay selection and beamforming

In this paper, we study virtual full-duplex (FD) buffer-aided relaying to recover the multiplexing loss of halfduplex (HD) relaying in a network with multiple buffer-aided relays, each of which has multiple antennas, through opportunistic relay selection and beamforming. The main idea of virtual FD buffer-aided relaying is that a source and a relay simultaneously transmit their own information ...
