Full Duplex Component-Forward Cooperative Communication for a Secure Wireless Communication System

Abstract

The technological breakthrough in the form of Internet of Things (IoT), Big data and connected world is increasing the demand of better spectrum utilization. Half-Duplex (HD) transmission is mostly used in the earlier communication systems. The high transmission demand requires the better utilization of the existing spectrum. There are several possible ways to overcome the problem of better spectrum usage. In-Band Full Duplex (IBFD) is one of the techniques that can double the Spectral Efficiency (SE) in a Beyond 5G (B5G) communication system. In this paper, our aim is to use the spectral efficient IBFD scheme to improve the security of the system with minimum interference. The interference can be reduced by the addition of orthogonality between the transmitted and received signal of a relay. A component-forward scheme is proposed in this paper to create such orthogonality. For achieving the desired aim, IBFD is used with Device-to-Device (D2D), Artificial Noise (AN), Modulation based orthogonalization, Radio Frequency Energy Harvesting (RFEH) and proposed Full-Duplex Component Forward (FD-CF) algorithm for multiple relays. We also use non-linear harvested power as one of the sources to reuse the exiting power for evaluating the system performance. The derivation of Secrecy Outage Probability (SOP) and throughput is derived in this paper for the FD-CF cooperative communication and is explored with and without non-linear RFEH. The simulation results show the comparison between the component-forward and decode-and-forward communication with one or more relays.

“…However, this algorithm is only applicable to a network with low density. In [13], the aim was to use the spectral-efficient IBFD scheme to improve the security of the system with minimum interference.

Inter-server computation offloading and resource allocation in multi-drone aided space-air-ground integrated IoT networks

“…In the following, both drone and MECS are collectively called 'drone' for easy presentation. All drones have the capability to communicate with both GIDs and other drones as well as satellites by adopting decode-and-forward (DF) scheme [25] and full-duplex technology, while each GID must leverage drone as relay to connect with the satellite. There are total 𝐾 types of computation tasks K Δ = {1, 2, ..., 𝐾 } requested by all GIDs, and each GID 𝑚 ∈ M has 𝐾 𝑚 types of task to execute, denoted by K 𝑚 Δ = {𝑘 𝑚,1 , 𝑘 𝑚,2 , ..., 𝑘 𝑚,𝐾 𝑚 }, where K 𝑚 ⊂ K, 𝐾 𝑚 < 𝐾.…”
