Now a day, Wireless communication systems are popular due to its wide advantages. In the customer’s point of view, we can say the most of the customer requirements related to communication from one place to another place are fulfilled up to the most extent using these systems. The initiation to these wireless communication systems started to satisfy the minimum requirements of the customers the...

There is no doubt that security mechanisms, such as authentication, are required in Information and Communication Technology, but they come at a price: Users need to spend additional time and effort to authenticate themselves. With this in mind, user perception of authentication is an important factor for successful use of authentication solutions. If users perceive an authentication procedure ...

To succeed in providing services, the quality of services should meet users’ satisfaction. This is a motivation to study the relationship between the service quality and the real perceived quality of users, which is commonly referred to as the quality of experience (QoE). However, most of existing QoE studies that focus on video-on-demand or IPTV services analyze only the influence of network b...

Multi-Protocol Label Switching (MPLS) technology has proven its worth for delivering new services while at the same time allowing migration from old to new generation networks. Avoidance of congestion is one of the major performance objectives of traffic engineering in MPLS networks. Load balancing can prevent the congestion caused due to inefficient allocation of network resources. Another imp...

This paper addresses the issue of evaluating the Quality of Experience (QoE) for Internet of Things (IoT) applications, with particular attention to the case where multimedia content is involved. A layered IoT architecture is firstly analyzed to understand which QoE influence factors have to be considered in relevant application scenarios. We then introduce the concept of Multimedia IoT (MIoT) ...

During recent years, for the ever-growing number of users with the exponential growth of high-data-rate traffic demand, quality of experience (QoE) has emerged as an important issue, providing important measures and assessment metrics for users, service providers and operators. Meanwhile, rapid development of information and communications technology significantly contributes to the increasing ...

Recent advances in computing and communication technologies enable the popularity of versatile mobile devices, which account for a substantial amount of energy use. The energy consumption has become of unprecedented importance not only from an economic perspective but also for the environment protection, particularly in a cloud computing systems which provide ubiquitous services. Conventional d...

Wireless Mesh Network (WMN) is an emerging technology that is gaining importance among traditional wireless communication scenarios. Wireless Mesh Networks are becoming a popular way of offering end-to-end services, such as Voice over IP (VoIP) and Video on Demand (VOD), in an inexpensive, practical, and fast manner. However, those applications require a minimum network performance level in ord...

To satisfy the increasing demand for multimedia services in broadband Internet networks, the WiMAX (Worldwide Interoperability for Microwave Acces) technology has emerged as an alternative to the wired broadband access solutions. It provides an Internet connection to broadband coverage area of several kilometers in radius by ensuring a satisfactory quality of service (QoS), it’s an adequate res...

Nowadays, with the continuous rise of Internet-based multimedia services, such as video sharing websites, web radios and IP-based telephony, multimedia communications are gaining more and more popularity. From the service provider's perspective, there is an increasing need in providing high-quality content; at the same time, from the network provider's view, the requirement is to design network...
