Future mobility management systems need to in-corporate innovative methods to improve mobile multimedia networking, such as quality-oriented decision-making functions for selecting the best Point of Attachment (PoA) for in-transit Moving Objects (MOs). Among the various correlating algorithms raised in the literature, solutions based on the Multiple Attribute Decision Making (MADM) are beneficial...
The edge computing techniques have been developed to support the exponentially increasing service demands in the fifth generation (5G) networks by bringing the data contents and their corresponding computations/communications near to mobile users. As a promising and efficient solution to implement edge computing techniques, mobile data offloading complements the traditional cellular transmission through...
Increasing demand in multimedia streaming has led to the advancement of Internet speed, reliability and other techniques. The 3GPP LTE network uses eMBMS protocol for broadcasting and multicasting the multimedia streaming, still the base station overloading has become an alarming issue due to the growing need of the mobile users. Since bandwidth is scares and limited, many emerging fields such as...
In this paper we examine a number of solutions used in developing multimedia guiding systems for travelers. We pay particular attention to existing mobile audioguide systems and the capabilities they provide for tour creators. The major contribution of this work is to propose a model that would be appropriate for better tour recommendation and playback automation of outdoor travel tours with using...
Multimedia clips, such as lecture recordings and screencasts, are increasingly used in both formal and informal learning contexts, such as flipped classroom, blended learning, MOOCs and mobile learning. In order to create effective educational multimedia applications, it is increasingly important to understand the factors contributing to the learning performance and learner experience. This paper...
The users' requests for online objects in mobile networks are characterized by fast varying dynamics caused by user mobility and diversity of users who produce contents. Conventional popularity methods cannot efficiently handle such strong dynamic requests of users, because they pay little attention to the time-varying user behavior which contributes to the growth and fading of online media files...
Future fifth generation (5G) wireless network will be driven by the large volumes of mobile data traffic, especially from enormous Machine Type Communication(MTC) devices but just use limited spectrum resources. In this paper, our fundamental motivation is to use less wireless resource at the cost of larger but acceptable transmission latency for massive clustering MTC devices. From the two observations...
The behavior that people change their cell phones is very important for phone manufactures and mobile operators to make commercial plans and competing strategies to attain maximum benefit. In this paper, we aim to evaluate four existing prediction models in phone changing events, based on user behavior data collected from one telecommunication operator. First we adopt the feature extraction algorithms...
Early childhood English teaching has become a hot topic with the development of informatization and economic globalization, which deserves the urgent attention of schools, teachers and parents. After analyzing the current status of early childhood English teaching, we found several problems including difficulty in inspiring children's learning interest, lack of teaching situation, and low study efficiency...
The focus of this study is to measure electronic learning technologies in Malaysian HEIs using the Importance-Performance Analysis (IPA) model. The Importance-Performance Analysis (IPA) is a model with a two-dimensional grid (satisfaction rating and importance rating) is divided into four categories: (1) Concentrate Here; (2) Keep Up the Good Work; (3) Low Priority; and (4) Possible Overkill, to enable...
The sovereignty of cloud-deployed media applications and services is improbable to be disrupted in the foreseeable future. This paper aims to provide an overview of the most essential technologies utilized by this constantly evolving cloud ecosystem, identify the design principles of a media-aware cloud and present an architectural position based on the research conclusions. An end-to-end quality-aware...
Transmission of high quality video over wireless networks is increasingly important as users consume more video on mobile devices. Improvement in display technologies will drive demand for higher quality experiences such as multiview video, at the expense of greater bandwidth requirements. The viewing experience can be disrupted while streaming video due to packet loss caused by network congestion...
Mobile Operators have experienced a growth of demand of new services with strict requirements and features which imposes challenges to operate the mobile wireless network. To tackle these challenges, Telcos must provide flexible, dynamic network architecture, furnishing resiliency to ensure end-to-end (E2E) service continuity in case of resource failures. Virtualization of the core network elements...
To address the challenge arising from mobile users' increasing demands for multimedia services, applying content caching in heterogeneous networks (HetNets) is regarded as an effective way to offload traffic and improve the capacity of mobile networks. In this paper, we aim at designing novel content caching strategies in HetNets to offload the network traffic and support users' requests locally....
In recent years, more and more internationally famous exhibition sites and scholars have actively engaged in research of mobile navigation system with the function of augmented reality (AR) display. However, most systems can be operated only when a special marker or image is shot at a close distance, and only one target can be recognized and displayed at a time, the function is limited. In particular,...
Providing proper technical solutions to cover all requirements of the Voice over LTE (VoLTE) service is still a great challenge for operators. Network monitoring is one of the important methods to support service verification, deployment and operations. The VoLTE service utilizes both the LTE Evolved Packet Core (EPC), and the IP Multimedia Subsystem (IMS). These architectures are built on different...
Recent advances in Virtual Reality (VR) technologies have resulted in a wider availability of Head Mounted Displays (HMDs). However, it is still unclear if VR gaming offers a substantial added value to players. For this reason a comparison of gaming experiences on VR HMD to those on mobile and PC, two other popular gaming platforms, is performed by conducting a user study via two games available on...
The Malaysian Ministry of Education has stated that the main objective of education is to produce students who possess higher order thinking skills (HOTS). For this purpose, students’ engagement in teaching and learning is of great concern. In the initiatives taken to help them towards achieving a better level of thinking, teaching and learning resource is one of the important factors to be considered...
Internet live broadcasting services such as USTREAM, TwitCasting have become popular. These services give broadcasters an ability which can broadcast videos via the Internet. By adding video effects and audio effects, live streaming services can realize as if broadcasters were in a different world. In this paper, we call this kind of live streaming 'Different Worlds Broadcasting'. However if many...
Mobile web browsing is becoming very popular with the recent advances in the satellite and wireless networks, and the growing popularity of the World Wide Web. The mobile users generally have limited resources, such as low bandwidth and low-resolution terminal, compared to the conventional desktop users. It is important to develop techniques that will enable the mobile users to access the web efficiently...
