In the next-generation wireless networks, cooperative communication is one of the auspicious techniques through which spatial diversity could be achieved by permitting the single antenna to act as virtual multiple input multiple output (VMIMO). The fundamental principle of cooperative communication was established on different types of relaying protocols and implementation of different relaying protocols according to the requirements of communication scenarios. The challenging task for achieving a high performance in cooperative communication is to find out the optimal relay node (RN) among different prevailing RNs. The basic purpose of cooperative communication is to maximize the performance of the network and minimize the overhead triggered by RNs by considering different communication metrics, i.e., signal to noise ratio (SNR), channel state information (CSI), and bit error rate (BER). This study presents a review of different cooperative relaying protocols with best relay selection techniques in the next-generation wireless network. Moreover, the different challenges faced by millimeter wave in 5G wireless networks and the role of cooperative communication to overcome those challenges are discussed. Turkey is that it transmits the duplicates of a signal to the destination independently. Many ideas regarding cooperative communication were first derived by Nichola et al. [5]. In the next-generation wireless network, cooperative communication may be one of the promising approaches for achieving the high data rates as well as efficient utilization of the bandwidth. Cooperative communication uses a RN, to provide coverage in the holes within the Long-Term Evolution-Advanced (LTE-A) cellular networks [6]. Similarly, in mm-wave communication that is considered in 5G, the relaying techniques are used to overcome different challenges of link blockage, backhaul connectivity, and path loss etc. Moreover, to make this technology more efficient and reliable, further improvements are required to achieve these goals.This study presents a broad overview of different relaying protocols with optimal relay selection methods used in different wireless networks. In addition, this study presents the potential benefits of using cooperative communication to overcome different challenges faced by the next generation of wireless networks. The remainder of this article is organized as follows. Section 2 presents existing research on cooperative communication. Section 3 gives an overview of cooperative communication, in which different relaying protocols are presented and comparison between them. In Section 4, we discuss the review of optimal relay selection techniques. In Section 5, we explain the different challenges faced by mm-wave and how to overcome them by cooperative communication. Section 6 summarizes the future challenges in cooperative communication and finally the conclusion is given in Section 7. Sami et al. [7] demonstrate a survey and taxonomy on medium access control for cooperative communication. This study classifies ...

“…But nontransparent relays are expensive and complex, and therefore most research studies are done for transparent relays which are more economical and easier to deploy. Another relay selection criterion is the mode of working principle of the relays like amplify-forward (AF) and decode and forward (DF) relays as a Study by Swain Manoj et al [29] propose relay selection scheme based on both AF and DF types of relays. The results show that the harmonic mean is better than min max scheme as far as SNR requirements for selection of relays is concern but for bandwidth performance min max supersedes harmonic mean.…”

Worldwide Interoperability for Microwave Access network accepts the challenge of last mile wireless access for internet. IEEE 802.16 standard, commercially known as WiMAX provide wireless broadband experience to the end subscribers and challenges many wired solutions like Digital Subscriber Line (DSL) and cable internet. Wireless network has many inherent issues like coverage holes; capacity optimization and mobility are few of them. Adding relays to multi-hop WiMAX IEEE 802.16j network present an effective solution to address them to some extent but this amendment does not elaborate any algorithm regarding the relay selection and narrate no performance guarantees. In this work, we proposed linear model that fairly allocates wireless resources among subscribers in 802.16j network. A relay selection algorithm is also presented to optimally select nodes with higher signal-to-noise ratio as relay station for nodes with lower signal-to-noise ratio objectively maximize overall network capacity. This scheme further extends network coverage area and improves network availability. We also did extensive performance evaluation of the proposed linear model. Results show that optimal relays selection scheme do provide a substantial increase of up to 66% in overall network capacity in the fixed WiMAX network. This improvement is substantial at places where network condition is not optimal. Investigating the problem further leads to the conclusion that the relay selection criterion is the key to achieve maximum network capacity.

This paper presents log likelihood ratio (LLR) based relay selection scheme for a cooperative amplify and forward relaying system. To evaluate the performance of the aforementioned system model, a three state Markov chain based fading environment has been presented to toggle among Rayleigh, Rician, and Nakagami-m fading environment. A simulation is carried out while assuming that there is no possibility of direct transmission from the source and destination terminal. Simulation results on the basis of Bit Error Rate (BER), Instantaneous Channel Capacity, and Outage probability have been presented and compared for different cases. In each case, the best performance of the proposed algorithm is obtained with a Binary Phase Shift Keying (BPSK) modulation scheme.
