Improved Buffer-Aided Multi-Hop Relaying with Reduced Outage and Packet Delay in Cognitive Radio Networks
2019
Electronics
Preserved Fulltext
By using the buffer-aided cooperative relaying, a cognitive radio network can enhance both the spectral efficiency and the range of the network; although, this could incur additional end-to-end delays. ...
When compared with other buffer-aided relaying schemes such as max-max, max-link, and buffer-aided relay selection with reduced packet delay, the proposed scheme demonstrated better interference mitigation ...
We would apply such a virtual full-duplex (VFD) relay scheme formed by two-half duplex relays in our proposed buffer-aided cognitive relaying scheme. ...

The performance of a cognitive radio network (CRN) can be enhanced through the use of cooperative relays with buffers; however, this incurs additional delays which can be reduced by using virtual duplex ...
In a virtual duplex mode, we mimic full-duplex links by using simultaneous two half-duplex links, one transmitting and the other one receiving, in such a way that the overall effect of duplex mode is achieved ...
A critical factor in a CRN with buffer-aided cooperative relaying is the selection of a suitable relay pair that can enhance its performance in terms of outage, throughput, and delay but improves spectral ...
