The IEEE Engineering Mobile Service Oriented Systems (EMSOS) Workshop aims to bring together researchers from academia and industry, as well as practitioners in the area of engineering services in mobile environments in order to provide a forum where recent research results can be presented and discussed. The objective is to understand open issues in the software engineering area of services applied...
Mobile operators are moving towards sharing network capacity in order to reduce capital and operational expenditures, while meeting the increasing demand for mobile broadband data services. Radio access network sharing is a promising technique that leads to reduced number of physical base station deployments (required for coverage enhancement), increased base station utilization, and reduced overall...
The increasing amounts of data requested by mobile client devices has given rise to broad research endeavors to determine how network providers can cope with this challenge. Based on real world data used to derive upper limits of web page complexity, we provide an evaluation of web browsing and localized caching approaches. In this paper, we employ two different user-browsing models for (i) individual...
WSNs are gradually penetrating all spheres of security, industry and civil sectors. Since the very inception of the concept, a need for enhancing energy efficiency and longevity of the networks is felt. Routing protocols designed for WSNs have evolved over the years in order to serve this purpose better. This paper summarizes the concerns of a WSN and discusses how these were addressed through innovations...
An operator-assisted user-provided network (UPN) has the potential to achieve a low cost ubiquitous Internet connectivity, without significantly increasing the network infrastructure investment. In this paper, we consider such a network where the network operator encourages some of her subscribers to operate as mobile Wi-Fi hotspots (hosts), providing Internet connectivity for other subscribers (clients)...
Aiming to meet the explosive growth of mobile data traffic and reduce the network congestion, we study Time Dependent Adaptive Pricing (TDAP) with threshold policies to motivate users to shift their Internet access from peak hours to off-peak hours. With the proposed TDAP scheme, Internet Service Providers (ISPs) will be able to use less network capacity to provide users Internet access service with...
Resource discovery strategy is an important part of mobile peer-to-peer network. How to response the users' query rapidly and effectively is related to the efficiency and the performance of the mobile P2P system. In this survey, we give an overview of the background and the characteristics of mobile P2P networks. We also provide a classification for mobile P2P networks, and review the corresponding...
With the accelerating development of aged tendency of population and rapid growth in the number of the disabled caused by diseases or injuries, the wheelchair with good performance for the aged and disabled is attracting the attention from the society. A wheelchair can provide the user with many benefits, such as maintaining mobility, continuing or broadening community and social activities, conserving...
Mobile Ad hocNetworks (MANETs) are becoming more important to wireless communications due to increasing popularity of mobile devices. The main challenge for future wireless networks is the quality of service for consumer satisfaction. The tool is supporting us with instant video transmissions such as video conferences and webinars. Multiple network hops are necessary to deliver and exchange data across...
Recently, the growth of mobile devices has brought great attention to the development of mobile apps. On the other hand, cloud hosting services provide an appropriate platform for mobile app developers so as to lower the cost of hardware maintenance and management. Note that most of current mobile apps are developed with a single cloud hosting, resulting in a higher probability of service congestion...
The dynamicity of modern communication networks relays on the switching and routing infrastructure. The Cloud, the Internet of Things, the Big Data, the mobile data communications, the 4k video all demand an even more dynamic network provided by high performance switching and routing infrastructure.
Estimation of binding lifetime has remarkable impact on the system performance. A longer binding lifetime may provide wrong information about the location of the mobile node where as a very short binding lifetime may cause network overheads in the form of higher exchange of binding refresh messages. The increase in message exchange intensifies the signaling load which in turn generates considerable...
In mobile ad hoc networks (MANETs), nodes usually have limited radio power and transmit in a very limited area. Communication beyond a node's radio range requires multiple hops between nodes, which in turn, requires nodes in MANETs to cooperate with each other in forwarding packets from a source to a destination. Problems in cooperation arise in self-organizing MANETs where selfish nodes exist. Selfish...
Smartphones are here to stay, transforming how we communicate, collaborate and share in our everyday lives, providing a wide variety of applications. Smartphones are becoming more affordable, 3G and 4G networks expand and mobile applications offer a convenient way to access information. The current study aims to investigate smartphone and smartphone applications utilization by university students...
This paper presents a new application model and a novel execution path-based algorithm for offloading in Mobile Cloud Computing (MCC) environments. Application offloading is the mechanism by which parts or modules of the application are executed in cloud remote computational services. Such operation saves resources in the mobile device but also incurs costs of accessing the cloud and using the communication...
Even in the absence of a physical network infrastructure, it is important that mobile devices can take advantage of the opportunities presented to them to maintain communication. Opportunistic networks are a class of mobile networks that must rely on unscheduled sporadic meetings between nodes to achieve communication. The main challenge in these networks is to route messages towards a destination...
In this paper, we study the problem of resource allocation for a multiuser orthogonal frequency-division multiple access (OFDMA) downlink with eavesdropping. The considered setup consists of a base station, several users and a single eavesdropper that indents to wiretap the transmitted message within each OFDMA subchannel. By taking into consideration the existence of the eavesdropper, the base station...
Cooperative techniques in wireless mobile networks typically leverage short-range communication technologies, e.g., WiFi, to allow data exchange between devices forming a mobile cloud. These mobile clouds have been considered as a key to reduce the cost of multicast services for the network operators as well as a means to deliver a better quality to the users. In fact, LTE-A includes Device-to-Device...
With the development of science and technology, lifelong learning and national education become the new education development direction. Ubiquitous learning is pervasive computing applications in the field of education and developed a kind of new education model, the design and development of learning resources have become an important support in ubiquitous learning.
