“…It is expected that D2D will an important communication method for 5G, especially to provide low latency between devices over short distances and minimal propagation delays. The potential of improving spectral utilization has promoted a lot of work in recent years, which shows that D2D can improve system performances by reusing cellular resources [18] and expected applications for D2D is peer-to-peer file sharing, voice, video streaming, and content-aware applications. Although there are benefits with D2D communication, some issues like direct discovery, interference management, and direct communication need to be properly addressed [19].…”

Abstract-With the growing interest in adoption of wireless technologies in industrial automation and the continuous search for new revenue streams new players are entering the arena in order to make their business grow further. One of the emerging wireless technologies aiming to support industrial automation applications is 5G, targeting anything from extreme throughput (> 10 Gbit/s) to extreme low latency (≤ 1 ms) to ultra high reliability (≥ 99.999%). In this article we intend to discuss the potential and challenges of adopting 5G in real industrial environments and give a more balanced picture compared to previous articles mainly written by telecom researchers and vendors as a way to promote their technology. Specifically, this article will discuss and provide some real industrial requirements, describe the main technical features of 5G and try to assess what applications it will support that are not by already supported by existing technologies. In the end, the success of 5G will depend on appealing business models and scalability, i.e., whether or not the same equipment can be deployed worldwide without any changes and spectrum rules, and the migration paths beyond 5G for reasonable business risks.

“…Also, one or several device may be used of relays for the other devices. Not having the eNodeB to control the communication between devices presents more challenges compare to the other model, such as resource allotment [8] [14], connection estblishment, relay selection, interference management, mode slection, [14], admission control and power allocation [18], cluster partitioning, and relay selection [19].…”

“…Therefore, the source and destination device have to use their resources in such a matter to ensure limited problems as DR-DC. Just like DR-DC, the devices will need to periodically broadcast identity information in order to let other devices know of their existence and decide whether or not they can start a D2D direct or device relaying communication [14] [6].…”

“…Only a few papers have considered power efficiency or energy efficiency for D2D communications. Power control is vital in achieving efficient energy usage and interference coordination in wireless networks [14]. Using to much power entails unnecessary levels of battery drain and interference to all other devices occupying the same signaling resources elsewhere in addition to the eNodeB [15], [16].…”

Abstract-The tremendous popularity of smart phones and electronic tablets has spurred the explosive growth of high-rate multimedia wireless services. To alleviate the huge infrastructure investment in the exponential growth of mobile traffic and improve local service flexibility, device-to-device (D2D) communications have been considered for the next generation mobile telecommunications. This has triggered investigation of fifth gernation (5G) to utilizes D2D communications for hetergenous networks. D2D communications enable users to transmit signals directly without going through the base station. However, many technical challenges need to be addressed for D2D communications to harvest the potential benefits. This requires learning how to improve the the model to better appeal to a wider base and move toward additional solutions. In this paper we provided a simple overview of D2D communications 5G hetergenous network by means of various Integer Linear programming. Finally, we present experiments on how Fractional knapsack using greedy algorithm can be used for power efficiency and improve throughput, thus allowing of future optimization problems.

“…INTRODUCTION Different from conventional cellular communications, where user equipments (UEs) communicate via the base station (BS), device-to-device (D2D) communications enable UE to communicate directly with other UEs in its vicinity using cellular resources [2]- [5]. D2D communications may potentially achieve three types of gains: proximity gain, reuse gain and hop gain [6].…”

Abstract-Device-to-device (D2D) communications in cellular networks enable direct transmissions between user equipments (UEs). If the source UE (SUE) and the destination UE (DUE) are far away from each other or the channel between them is too weak for direct transmission, then multi-hop D2D communications, where relay UEs (RUEs) forward the SUE's data packets to the DUE, can be used. In this paper, we propose an energyefficient optimal adaptive forwarding strategy (OAFS) for multihop D2D communications. OAFS adaptively chooses between the best relay forwarding (BRF) mode and the cooperative relay beamforming (CRB) mode with the optimal number of RUEs, depending on which of them provides the higher energy efficiency (EE). To reduce the computational complexity for selecting the optimal RUEs for CRB mode, we propose a low-complexity suboptimal adaptive forwarding strategy (SAFS) that selects between the BRF and the CRB with two RUEs by comparing their EE. Furthermore, a distributed forwarding mode selection approach is proposed to reduce the overhead for forwarding mode selection. The analytical and simulation results show that OAFS and SAFS exhibit significantly higher EE and spectral efficiency (SE) than BRF, CRB, direct D2D communications and conventional cellular communications. SAFS is almost as energy-and spectral-efficient as OAFS.
