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...

In wireless two-way (TW) relay channels, denoise-and-forward (DNF) network coding (NC) is a promising technique to achieve spectral efficiency. However, unsuccessful detection at relay severely deteriorates the diversity gain, as well as end-to-end pairwise error probability (PEP). To handle this issue, a novel joint cyclic redundancy code (CRC) check method (JCRC) is proposed in this paper by ...

In this paper, we investigate an opportunistic relay and jammer scheme along with relay selection algorithms based on the secrecy rate criterion in multiple-input multiple-output buffer-aided down link relay networks, which consist of one source, a number of relay nodes, legitimate users and eavesdroppers, with the constraints of physical layer security. The opportunistic relay and jammer schem...

Although many PID tuning approaches are available, it is not easy to find a method that does not require any engineer/operator interference. In this work, we present a fully automated approach for PID tuning based on relay feedback. This method involves sending the relay feedback test data from PLCs (Programmable Logic Controller) into a historian, analyzing the test data using a tuning applica...

Blind-spots, where wireless signals do not reach within the coverage range, often emerge in a dynamic environment due to obstacles, geographical location or mobility of cellular users (CUs). Thus greatly reducing overall system performance terms and throughput. Relay-aided cognitive Device (cD2D) communication underlying 5G network can help mitigate blind-spots. Cognitive capability helps D2D a...

The secure wireless communication has been an important field of research. The proposed max-ratio relay selection techniques introduced to security of transmission in buffer aided cooperative wireless network. The data transmitted from source to relay and relay to destination. An eavesdropper can used to intercept the data from source to relay and relay to destination. Assume, data buffer are a...
