Sector-Based Radio Resource Allocation (SBRRA) Algorithm for Better Quality of Service and Experience in Device-to-Device (D2D) Communication

Abstract

IEEE Transactions on Vehicular Technology 1  Abstract-The mounting content sharing among users has resulted in a considerable rise in wireless data traffic, pressurizing the cellular networks to undergo a suitable upheaval. A competent technology of the fifth-generation networks (5G) for efficiently supporting proximity-based applications is Device-to-Device (D2D) communication, underlaying cellular networks. Significant advances have been made till date, for allocating resources to D2D users in cellular networks, such that sharing of spectral resources between cellular and D2D users is carried out in a coordinated manner. In this paper, a sector-based radio resource allocation (SBRRA) algorithm for resource block allocation to D2D pairs has been proposed, where the number of resource blocks (RBs) is allocated to each D2D pair in an adaptive manner, based on the demanded application by each pair. Different applications demand a varying number of RBs, in accordance with their priority. This algorithm focusses on the use of sectored antennas at the base station, for a better performance and low complexity. Extensive simulations are carried out, considering real-time scenario, for ensuring satisfactory Quality of Service (QoS) and Quality of Experience (QoE) by the users. The efficiency of the proposed scheme is proved by comparing it with the RB allocation using Hidden Markov Model (HMM).

E2ARC: Energy‐efficient adaptive resource block allocation with low complexity in device‐to‐device communication

“…Sectoring the cellular coverage reduces interference, markedly improving the performance of the cellular network. Other sector‐based schemes for optimal resource allocation in D2D networks have been proposed in the work of Gandotra et al and Ni et al, achieving significant improvement in throughput. Since improved network performance is achieved through cell sectoring, this paper instigates sectoring of cells.…”

“…The process of addition of throughputs, as in (9), is given in lemma 1 in the work of Gandotra et al From (9), it is clear that the proposed scheme boosts the overall throughput. Computing the throughput as an average over q iterations, the system throughput is given as…”

“…Cell sectoring has also been observed to improve the QoS requirements in a WCN by reducing the interference and assuring optimal resource availability. Considering a sectored cell with each sector being 120 0 , a general resource block (RB) sharing scenario is depicted for a single sector in Figure .…”

“…The WCNs are experiencing an exponential rise in the subscriber count and their demanded applications, which has brought about the notion of 5G WCNs. The QoS and QoE considerations in 5G WCNs are intensifying and are pre‐eminent for the mobile network operators as well as the mobile terminals (MTs), with an overall low complexity. To meet the user requirements, various technologies are blossoming, which includes ultradense networks, IoT, and others.…”

A Two-Layer, Energy-Efficient Approach for Joint Power Control and Uplink–Downlink Channel Allocation in D2D Communication

“…With the rapid development of the Internet of things (IoT) and cellular technology, the demand for higher data rates and radio spectrum resources has continued to increase over the past decade [1,2]. As one of the critical technologies of 5G [3], device-to-device (D2D) communication is a short-distance, low-power communication technology that enables dialogue using direct links and omnipresent information interaction [4,5]. Underlaying general cellular networks, D2D communication brings multiple benefits to network capacity and significant performance improvements to the user experience [6,7].…”
