“…From [29], we agree that path loss is dependent on the deployment environment with urban environment exhibiting higher losses. This is since urban environments experience more obstructions in their signal path which in turn degrades the SINR.…”

The growing demand for bandwidth and spectrum has inspired the ongoing efforts to establish the future 5G network supporting vertical sectors such as cyber-physical systems (CPS). Cooperative communication is one of the requisite techniques to improve coverage, network capacity and reduce power consumption in the network. In this paper, a symbiotic two-phase intelligent transmission is considered. The first phase occurs between the source and the candidate relays, and involves the selection of a set of “reliable relays”. The second phase occurs between the reliable relays and the destination, and involves the selection of the “best relay” for transmission. Dynamic relay selection using k-means clustering is used to detect the most significant correlation between all the channel state information (CSI) attributes in the system. The work identified the reliable relays while reducing the number of relay nodes for the second transmission phase. Contextual scenarios are created with typical network configuration using three geographical locations Coventry, Birmingham and London. An experimental validation is done with Omnet++ environment for the scenarios of three geographical locations. A natural grouping of mobile users is carried out leveraging the relay capabilities. The results are validated using support vector machine (SVM) classification algorithm. Considering urban environment deployment of relay nodes, metrics such as signal-to-noise-plus-interference ratio (SINR), attenuation, signal to noise ratio (SNR), link quality, k-means clustering, accuracy, and root mean square error (RMSE) are investigated for the Direct-2-Direct (D2D) capable relays. It was observed that the proposed technique both outperforms the other fixed-parameter relay selection techniques and improves with larger datasets unlike the other techniques.

“…Authors in [3] state future challenges as link adaptation with a variety of channel state information such as capacity, signal and noise ratio (SNR), plus with different coding schemes such as a trellis, and space-time block coding. Authors in [4] concluded that inter-site distance plays an important role in the system as it affects the path loss and the SINR of the system. In [5], authors describe various ways for the resource allocations, methods of link adaptation (including power control and rate control), both with adaptive modulation and coding and hybrid automatic request.…”

“…In [12] authors discuss the challenges in scheduling user transmissions for the downlink of an LTE network; they propose proportional fair and suboptimal proportional fair scheduler and measure performance in terms of throughput and SINR. In [13] the authors have described a Signal-to-Noise-plus-Interference Ratio (SINR) for a different type of radio terrain, as per their results obtained in a rural environment the value of SINR quite better in comparison with an urban. And as per their result, add-on relay nodes (RN) in LTE systems would provide a better solution to optimize the problems of path loss and SINR at the cell boundaries.…”

The requirement of the wireless network is increasing with the developments in every field of society. As it helps to use contactless controls and communications with different applications. From the fifth generation and beyond, the need of wireless networks is to fulfil the capacity requirement and offered better connectivity between peer entities. To offer high throughput within the wireless network, beamforming is one among the optimum solutions that provides better connectivity and bandwidth among peer entities. In the work, we assessed the wireless capacity of beamforming wireless network using the Frequency Division Duplexing (TDD) and Time Division Duplexing (TDD) type for multiple Transmission Modes (TM) under different radio conditions. We modify the channel properties with respect to varying the Signal to Noise Ratio (SNR) and measured the performance of both systems independently in terms of throughput, and Block Error for both the duplexing using quantitative and ratio analysis. Further, we conclude that the beamforming for higher TMs offered high throughput in best to worst channel conditions.
