Long Terrn Evolution (LTE) can be called as the new generation of High Speed Cellular Communication. LTE networks serves as back bone for 4G networks delivering high data transmission speeds and support for Qualisty of Service (QoS). It also ensures the availability of high speed connection, HD Calling, more security and extended support for streaming of HD multimedia content which includes audio and video content. With this much development in the field of mobile communication, another term was coined QoE (Quality of experience) which refers to the overall degree of acceptability of the multimedia content as perceived by the end users. In this paper we introduce a CQI based algorithm to improve the overall QoE while it is being applied on downlink scheduling. Simulation runs proves that CQI has better results as compared to other algorithms based upon parameters such as throughput, SnR and fairness.

Medical Quality

It is well known that the evolution of 4G-based mobile multimedia network systems will contribute significantly to future m-health applications that require high bandwidth, high data rates, and more critically better Quality of service and quality of experience. The key to the successful implementation of these emerging applications is the compatibility of emerging broadband wireless networks such as mobile WiMAX, HSUPA, and LTE networks with future m-health systems. Most recently, the concept of 4G-health is introduced. This is defined as the evolution of m-health towards targeted personalized medical systems with adaptable functionalities and compatibility with future 4G communications and network technologies. This new concept represents the evolution of m-health toward 4G mobility. It will have new challenges especially from the next generation of mobile communications and networks perspective and in particular from relevant quality of service and quality of experience issues. This chapter presents some of these challenges and illustrates the importance of the new concepts of medical Quality of Service (m-QoS) and medical Quality of Experience (m-QoE) for 4G-health systems. The chapter also presents a validation scenario of these concepts for medical video streaming application as a typical 4G-health scenario.

We introduce a real-time experimentation testbed in this paper which enables more realistic analysis of quality of service (QoS) in LTE networks. This testbed is envisioned for the improvement of QoS and quality of experience (QoE) through the experimentation with real devices, services, and radio configurations. Radio configurations suggested in the literature typically arise from simulations; the testbed provides a real and controlled testing environment where such configurations can be validated. The added value of this testbed goes a long way not only in the provision of more realistic results but also in the provision of QoS and QoE cross-layer measurements through the correlation of information collected at different layers: from service and IP levels to radio and protocol parameters. Analyzing the interlayer dependencies will allow us to identify optimal settings for the radio access network and service parameters. This information can be used to suggest new cross-layer optimizations to further improve quality of experience of mobile subscribers. As a use case, we examine VoIP service over LTE, which is currently an open issue.

The development of Internet use has spurred Wireless Sensor Networks (WSNs) technology so that it becomes a widely researched and applied device. With the need to use high WSNs, the quality of features provided such as high data transfer speeds and the smallest possible disruption is something that should be available. Although some uses of WSNs do not require high speed and have a tolerance for interference, there are very few types of use. Nevertheless, routing protocols are provided to meet the types of data transfer requirements. The protocols available for each type will be analyzed and compared to find out the best performance.Keywords: data transfer, routing protocol, WSN.

AbstractNon-orthogonal multiple access (NOMA) technology provides an effective solution to massive access with a high data rate demand in new-generation mobile networks. The paper combinations with NOMA and simultaneous wireless information and power transfer (SWIPT) relay to maximize the sum rate in the downlink system. To that end, it is critical how to select effectively users access system and power allocation for the access user. This paper proposes a user selection and dynamic power allocation (USDPA) scheme in the NOMA-SWIPT relay system based on neural network because traditional optimization methods have difficulty solving nonlinear and non-convex problems. We establish a user selection network utilizing a deep neural network (DNN) and propose a power allocation network using deep reinforcement learning. The simulation results show that the proposed scheme achieves better performance than other related schemes, especially for high quality of service requirements.

Guaranteeing Quality of Service (QoS) to mobile users is the primary aim of cellular broadband system like Long Term Evolution (LTE). Radio resource allocation and scheduling are two important functions in the LTE networks to enhance the quality of service. For increasing the generally user experience, an efficient radio resource allocation and Scheduling algorithm should be used. However, this became a non-trivial task as the demands and requirements of user data changes day-to-day. In these situations, with the limited radio resources, maximum system capacity can be obtained on expense of unfair share of the resources. In this work, high speed cell edge users are considered as they experience poor signal strength and their quality of service degrades when they move away from Evolved-Nodes (e-Nodes). Here, a novel scheduling algorithm has been introduced to extend the cell edge throughput amid during high mobility scenarios. The proposed scheduling scheme will be compared with the conventional schemes like best CQI, RR and PF in terms of throughput and fairness. It is presented that the proposed scheme gives better performance against the conventional ones in the chosen scenario.

Year after year, the growth of video traffic over the Internet keeps increasing. Video streaming over best-effort networks is considered inefficient and inappropriate to meet the expected Quality of Experience (QoE) of the new generation of multimedia services. Over the past few years, a number of technologies have emerged to improve the state of the art of video delivery, including HTTP Adaptive Streaming (HAS) that adapts the bitrate according to network conditions. At the crossroads, Software Defined Networking (SDN) offers options to meet Quality of Service (QoS) objectives for improved video quality by exploiting end-to-end programmability of network behaviour. However, traditional SDN approaches require dealing with low-level details from the underlying infrastructure, interfering in the automation and agility of service deployments. To alleviate these issues and overall provide a simpler approach, Intent-Based Networking (IBN) is being proposed to abstract low-level configurations through high-level policy interfaces. In this paper, we explore such an approach by implementing intent-based control loops for video service assurance. The proposed methods dynamically reconfigure the network for service-specific requirements using IBN to define the high-level behavior. We experimentally evaluate a use case where video traffic is rerouted based on network conditions to improve the QoS. The Proof-of-Concept results point to the potential of improving video content delivery through QoS-aware Intent-based approaches.
