Book Description
The analysis of QoE is not an easy task, especially for multimedia services, because all the factors (technical and non-technical) that directly or indirectly influence the user-perceived quality have to be considered. This book describes different methods to investigate users’ QoE from the viewpoint of technical and non-technical parameters using multimedia services. It discusses the subjective methods for both controlled and uncontrolled environments. Collected datasets are used to analyze users’ profiles, which sheds light on key factors to help network service providers understand end-users’ behavior and expectations. Important adaptive video streaming technologies are discussed that run on unmanaged networks to achieve certain QoS features. The authors present a scheduling method to allocate resources to the end-user based on users’ QoE and optimizes the power efficiency of users’ device for LTE-A. Lastly, two key aspects of 5G networks are presented: QoE using multimedia services (VoIP and video), and power-saving model for mobile device and virtual base station. Features two proven methods to collect datasets for assessing the user's QoE Investigates client-based HTTP rate adaptive video streaming algorithms over TCP protocol to regulate the user's QoE Discusses VoIP service and focuses on a QoE driven downlink scheduling method for LTE-A technology Introduces the concept of 'quality of experience' presenting all parameters which directly or indirectly influence the user’s satisfaction within two well-used Internet services, multimedia OTT streaming and Voice over IP

Book Description
Beginning with the first event in 2002, the International Conference on Wired/ Wireless Internet Communications (WWIC) has continuously been established as a highly selective conference focusing on integration and co-existence of rapidly dev- oping wireless network technologies and their applications related to the Internet. To do so WWIC provides an international forum for presenting and discussing cutti- edge research in this domain, and the 8th edition of WWIC, held at Luleå University in June 2010, continued this tradition. The WWIC 2010 call for papers attracted 45 submissions from more than 25 countries and each contribution was subject to thorough peer review by recognized int- national experts that acted as members of the Technical Program Committee. The selection process resulted in 16 accepted papers, which were thematically grouped into 5 technical sessions. The major themes of WWIC 2010 were cooperation, management of multimedia traffic, advancing IEEE 802.11, cognitive optimization, mesh and multi-hop networks, security, signaling, control, and wireless sensor networks.

Book Description
The main objective of the book is to present state-of-the-art research results and experience reports in the area of quality monitoring for customer experience management, addressing topics which are currently important, such as service-aware future Internet architecture for Quality of Experience (QoE) management on multimedia applications. In recent years, multimedia applications and services have experienced a sudden growth. Today, video display is not limited to the traditional areas of movies and television on TV sets, but these applications are accessed in different environments, with different devices and under different conditions. In addition, the continuous emergence of new services, along with increasing competition, is forcing network operators and service providers to focus all their efforts on customer satisfaction, although determining the QoE is not a trivial task. This book addresses the QoE for improving customer perception when using added value services offered by service providers, from evaluation to monitoring and other management processes.

Book Description
This is an important and timely book. Students of organizational behavior for the last 15 years have been asking how to integrate the technology of data gathering and data analysis with critical organizational challenges. This book shows how to do that, using the field of customer service to illustrate the broader point. This volume allows lay readers to understand telemetry and helps them enhance their data-gathering activities to strengthen customer relations. Author of The Agenda Mover: When Your Good Idea Is Not Enough and Transforming the Clunky Organization: Pragmatic Skills for Breaking Inertia (Cornell University Press) Telemetry is an automated way of collecting data at remote sites or locations, and transmitting it to collectors at receiving site for monitoring, analyzing, and driving improvement actions. This book provides the necessary knowledge and information to understand the telemetry infrastructure and associated details. It will enable readers to implement a telemetry program to address customer experience pain and improve customer experience. The authors of this book have all served in different roles and capacities in one of Silicon Valley's premier technology companies. These roles include software engineering, customer assurance, quality management, technology development, and implementation. Their paths intersected in the area of quality management, and they have witnessed first-hand how the latest technology/market transitions around Internet of Things (IoT), digitization, and telemetry are impacting the company they work, as well as the high-tech industry and global economy as a whole. The real-time nature of data and the advent of machine-learning algorithms have set the stage for a new era that the authors call adaptive customer experience. The premise of this concept is that real-time availability of customer experience data opens the door for real-time responses based on machine-learning algorithms. This creates an unprecedented opportunity to change the relationship between customers and the systems they depend on in their digital world. The proliferation of sensors and improvements in data science capabilities are creating an environment where the possibilities for telemetry are limitless. The book provides several examples of use cases and applications that help bring telemetry to life.
