Device-to-device (D2D) communication has been widely studied to improve network performance and considered as a potential technological component for the next generation communication. Considering the diverse users' demand, Quality of Experience (QoE) is recognized as a new degree of user's satisfaction for media service transmissions in the wireless communication. Furthermore, we aim at promoting user's Mean of Score (MOS) value to quantify and analyze user's QoE in the dynamic cellular networks. In this paper, we explore the heterogeneous media service distribution in D2D communications underlaying cellular networks to improve the total users' QoE. We propose a novel media service scheme based on different QoE models that jointly solve the massive media content dissemination issue for cellular networks. Moreover, we also investigate the so-called Media Service Adaptive Update Scheme (MSAUS) framework to maximize users' QoE satisfaction and we derive the popularity and priority function of different media service QoE expression. Then, we further design Media Service Resource Allocation (MSRA) algorithm to schedule limited cellular networks resource, which is based on the popularity function to optimize the total users' QoE satisfaction and avoid D2D interference. In addition, numerical simulation results indicate that the proposed scheme is more effective in cellular network content delivery, which makes it suitable for various media service propagation.

“…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].…”

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.

Resource Allocation Scheme for D2D Communications in Multi-Cell Environments

In order to solve the inter-cell interference, the proposed scheme allocates the pre-assigned resource group and shares the information with neighbor cells. This paper also proposes a power control scheme for D2D communication to enhance the cell throughput. By the simulation results, the average SINR of the cellular uplink and D2D communication link are mostly higher than 10 dB when the proposed scheme is applied. On the other hand, with the inter-cell non-coordinated resource allocation scheme, the average SINR of the D2D communication link are decreased by 0 dB. In addition, the proposed scheme can enhance the cell throughput up to 8 % compared with the inter-cell non-coordinated resource allocation scheme.
