This chapter discusses the various issues that surround the development stage of mobile TV services. It highlights the importance of Quality of Experience (QoE), which is a shift in paradigm away from the widely studied Quality of Service (QoS). We discuss the factors affecting QoE and the types of assessment methods used to evaluate QoE. A QoE-layered model is presented with the aim of ensuring end-to-end user satisfaction. Using a case study, we develop a QoE management framework. We argue that gaining an understanding of users’ perceptions and their service quality expectations may assist in the development of QoE models that are user centric.

Qos Monitoring

Abstract The paper presents a new concept, Usability Monitoring, and applies it for situational awareness applications in military Command, Control, Communication, Computers, Intelligence, Surveillance and Reconnaissance systems (C4ISR). Usability Monitoring means taking measurements of technical Quality of Service (QoS) parameters in end systems and comparing them to target values of reference cases. The concept differs from QoS monitoring in the goal and in the placement of measurement points: In QoS monitoring the goal is to verify that the network provides the promised service quality in the user system - network interface. QoS monitoring does not capture the actual end user experience, which is influenced also by the end system, and therefore it does not directly correspond to the service quality that a user sees. Usability Monitoring has exactly this goal. The Observe-Orient-Decide-Act-Loop (OODA) is a decision making concept that is widely used in the network-centric approach and it emphasizes fast decision making. The presented model for Usability Monitoring is based on the OODA-loop. It includes QoS measurements not only in the Act-phase, i.e., can the user perform the actions s/he wants or are there delays and losses that make the system less usable, but also in the Observe-phase, i.e., does the user get the information s/he subscribes to, and in the Orient-phase, i.e., does the user get confusing information and cannot orient, and also the Decide-phase, i.e. is the user able to make right decisions based on the previous steps. The measured technical QoS parameters are connected to user experience by Mean of Score (MOS) functions that are obtained by usability tests. A case study for partially evaluating the Usability Monitoring concept is from MNE5 MSA (Multinational Experimentation 5, Maritime Situational Awareness) Experimentation Event 3 that was conducted in partnership with the Navy Command Finland, Naval Warfare Centre of Sweden and NATO Allied Command Transformation (ACT) and the Singaporean Armed Forces (SAF) Future Systems Directorate. In the MNE5 MSA experimentation we were able to monitor end user experience, how the user sees the services and is able to work with the current tools and capabilities. In this article we describe how Usability Monitoring was addressed in the MNE5 MSA case study: meters for Usability Monitoring were selected and we investigated what aspects of usability affect the phases of the OODA-loop.

Electronic Government (e-Government) has been implemented in Indonesia at both the central and regional levels, where Information and Communication Technology (ICT) is integrated with public services in order to increase effectiveness, efficiency, and transparency. Surakarta has succeeded in creating an application that operates online which can be used to access population administration services, namely Dukcapil application (Dukcapil dalam genggaman in Indonesian term). This application is designed to make it easier for some people of Surakarta who are still experiencing problems if they have to directly access population administration services, whether constrained in terms of time, energy, and cost. As part of population administration services and population information systems, user satisfaction is important for Dukcapil Dalam Genggaman because it is related to the quality of the services provided and the success of implementing the application. User satisfaction can be influenced by several factors. Therefore, this study will examine the factors that influence user satisfaction of Dukcapil Dalam Genggaman. These factors were adapted from a model for measuring the level of user satisfaction with information systems, namely End User Computing Satisfaction (EUCS), which measures satisfaction based on content, accuracy, format, ease of use, and timeliness. This study aims to determine the effect of these factors on user satisfaction of Dukcapil Dalam Genggaman. The questionnaire was distributed to users of Dukcapil Dalam Genggaman and successfully obtained a sample of 107 users. The data analysis used is multiple linear regression. It was found that content, accuracy, ease of use, and timeliness have a significant effect on user satisfaction of Dukcapil Dalam Genggaman. Meanwhile, the format does not have a effect on user satisfaction of Dukcapil Dalam Genggaman. Based on these findings, the Department of Population and Civil Registration of Surakarta is recommended to develop Dukcapil Dalam Genggaman by focusing on the factors that affect user satisfaction of the application.

Network applications demand quality of service for enhanced call quality and increased user satisfaction. Hence, implementing queuing discipline at switches and routers in a network will govern the way packets are buffered while waiting for transmission. Queuing disciplines like first-in first-out (FIFO) queuing, priority queuing (PQ), weighted-fair queuing (WFQ), custom queuing and modified weighted round robin are more prominently deployed in network applications. These queuing disciplines help to control and manage network resources by fixing priorities for specific types of data on the network. The paper aims to analyze the quality of service parameters for various real time applications like File transfer protocol(FTP), email, database, Voice over IP(VOIP), video and web browsing,etc., and helps to optimise the use of available network resources. Moreover the quality of the network is compared using different QoS parameters such as end-to-end delay, throughput, jitter and Mean Opinion Score (MOS). This paper focuses on various queuing disciplines with low and high network traffic.

Public involvement in transportation infrastructure decision making is frequently mandated and is regarded as increasingly essential by a wide variety of stakeholders. The integration of advanced technologies, such as visualization, into this process is increasingly desired. However, public involvement processes often are regarded as problematic by many stakeholders and the state highway agencies charged with implementing them. Structured public involvement (SPI) is posited. SPI takes a systems approach toward the integration of advanced technologies into public involvement forums. Because the goal of public involvement is to increase user satisfaction with both the process and the outcomes, the characteristics of advanced technologies and their capacities for gathering useful feedback in public forums must be evaluated. Visualization is put forth as an enabling technology within an SPI framework. The properties, capacities, and transportation-related uses of three visualization modes are evaluated, and their operational features are discussed. A case study dealing with highway improvement in central Kentucky reveals that three-dimensional renderings are significantly preferred to twodimensional and virtual reality modes; the case study also shows that visualization should complement, not replace, other performance information. The role of electronic scoring as an integral component of this SPI protocol is emphasized, resulting in fast assessment and free expression of views. Factors affecting the efficiency of visualization are analyzed, and recommendations are presented for implementing SPI protocols that rely on visualization. These include investigating participants' previous experience with visualization, incorporating iterative public involvement in finalizing design options, and ensuring that the technologies are compatible with the chosen public involvement process.

In sport context, many contributions are involved in the perception of quality and satisfaction in sport services, but in regards to brand perception, such studies are much less common. Virtually no work is aimed at brand awareness of sports services. In the book chapter the authors expose a case study that analyze the users perception of the image of the service and is related to some performance indicators such as quality of service, satisfaction and future intentions. Data analysis is performed using structural equations and measurement scales adapted to sports facilities. The results of this study show that quality is explained by congruence with a high percentage of variance (76.6%), the latter concept being the aspect with the greatest predictive weight. Furthermore, future intentions are explained by attitudes towards the brand and quality, the latter being the element with greater predictive power.

Near Future

Video streaming is expected to acquire a massive share of the global internet traffic in the near future. Meanwhile, it is expected that most of the global traffic will be carried over wireless networks. This trend translates into considerable challenges for Service Providers (SP) in terms of maintaining consumers' Quality of Experience (QoE), energy consumption, utilisation of wireless resources, and profitability. However, the majority of Radio Resource Allocation (RRA) algorithms only consider enhancing Quality of Service (QoS) and network parameters. Since this approach may end up with unsatisfied customers in the future, it is essential to develop innovative RRA algorithms that adopt a user-centric approach based on users' QoE. This chapter focus on wireless video over Critical communication systems that are inspired by QoE perceived by end users. This chapter presents a background to introduce the reader to this area, followed by a review of the related up-to-date literature.

In this chapter, the authors present some of the latest developments related to the provisioning of Quality of Service (QoS) in today’s networks and the associated network management structures that are or will be deployed to support them. They first give a brief overview of the most important Quality of Service proposals in the areas of Layer 2 (L2) and Layer 3 (L3) QoS provisioning in backbone networks, and they discuss the network management structures and brokers that have been proposed in order to implement these services. As a case study, they describe the pan-european research and academic network, which is supported centrally by GEANT and which encompasses multiple independent NRENs (National Research and Education Networks). In the last few years, GEANT has developed and deployed a number of production and pilot services meant for the delivery of quality network services to the end users across Europe.
