Mobile devices are ubiquitous but their resources are limited. However, they must be capable to run computationally intensive software, for example for image stitching, face recognition, and simulation-based artificial intelligence. As a solution, mobile devices can use nearby resources to offload computation. Distributed computing environments provide such features but ignore the nature of mobile...
Web services bring more conveniences for users and developers. However, it makes user face the problem of service information explosion. The personalized service recommendation solves the problem. This paper proposes a method to predicting the system reliability which bases on user context information in mobile computing environment. The method construct user behavior model by formatting user location...
With the expansion of mobile computing and mobile data services, the number, type, and application of location-based services will continue to expand rapidly in the coming years. These apps have attracted the interest of users from different fields, such as gaming, mobile commerce, navigation systems, emergency services, and various tracking systems. As these apps use large volumes of location data...
With the rise of smart mobile devices, context-aware mobile applications became an integral part of our everyday life. However, testing, evaluating or demonstrating context-aware mobile applications for outdoor environments remains a resource-intensive and cumbersome task. The investigations need to be conducted in real-world experiments in order to gain proper insights into how well an application...
The human daily and the professional life demand a high amount of communication ability, but every fourth adult above 50 is hearing-impaired, a fraction that steadily in- creases in an aging society. For an autonomous, self-condent and long productive life, a good speech understanding in ev- eryday life situations is necessary to reduce the listening ef- fort. For this purpose, a mobile app-based...
As wireless communication and mobile devicesadvances, recommendation system is one of the keytechnologies to realize personalized service. This paperproposes a service recommendation mechanism using aprobabilistic model in mobile devices. With the contextualinformation and the use's demand state inferred by the model, we can recommend a service to meet the user's preferencesand needs at real time...
Mobile cloud computing (MCC) is the most promising cloud solution for the future mobile environment. It aims to integrate mobile devices with cloud computing, and provide to mobile users an online access to unlimited cloud resources. Furthermore, MCC has changed the concept of mobile devices from primitive gadget to full computers that accommodate work, personal and mobility needs. Thus, in this paper...
Cloud Radio Access Network (C-RAN) is a novel mobile network architecture that brings baseband processing units (BBUs) of a set of base stations into a central server keeping only remote radio heads (RRHs) at the cell sites. Because of their limited resources, running sophisticated applications on mobile handsets could result in poor performances and shortened battery lifetime. One promising solution...
The widespread use and increasing capabilities of mobiles devices are making them a viable platform for offering mobile services. However, the increasing resource demands of mobile services and the inherent constraints of mobile devices limit the quality and type of functionality that can be offered, preventing mobile devices from exploiting their full potential as reliable service providers. Computation...
The resource demands of specific services develop as well along with the increase of mobile. Nonetheless, mobile certainly will often be restricted performance that is regarding computation, storage, battery life, context adaptation of connectivity, scalability, and heterogeneity included security issue. An outstanding solution to address these limitations is definitely to offload computation is mobile...
Mobile context-aware computing is an essential component of the smart cities infrastructure. Attempts were made to develop a model that can effectively represent a system in device to support context-aware behavior. The purpose of this paper is to identify deficiencies of the previously developed model and propose solutions to improve it.
For the last decade, researchers are showing interest in mobile cloud computing (MCC) for its promising potentiality. It combines cloud computing and mobile computing providing better quality of service to user with mobile device. Resource famished applications can now be executed on mobile devices by offloading the task on cloud. Major research areas in MCC are how, where and when to offload a task...
The Home Subscriber Server (HSS) within the packet core of the Long Term Evolution (LTE) is a key node leveraged for essential operations, such as mutual authentication and access control. This centralized node is essential for the overall network operation as it is the cornerstone of the cryptographic functions executed in a mobile network. It stores several parameters for each subscriber, including...
Microinteractions provide small details that may have a big impact on user experience of a (software) product. There are many examples of successful implementation of microinteractions in traditional software products, such as cut & paste functionality. However, the increasing popularity of mobile and wearable computing devices increases its application area and provides new opportunities to discover...
In the present mobile climate, both companies as well as their consumers are able to execute various processes at any time in any location using a myriad of wireless technologies. Organizational trends demonstrate that mobile devices are being utilized exponentially more to solve problems from the strategic planning level to the operational level through various departments. This propensity was recently...
Today, mobile phones due to the rapid growth of new technologies and the emergence of a new generation of smart phones have become more than a communication tool that not only resolves the user's communication needs, but also provide them, services for many applications. List of mobile phone subscribers include slow-level simple concepts such as time and place of calls, talk time, etc. The analysis...
The recent years have seen a vast growth of location-based services (LBS) usage with the ubiquity of smart mobile devices. While reactive LBS act on the user's request, proactive LBS notify the user proactively of relevant location-specific content in case a dedicated area is entered. The usage scenarios of proactive LBS vary from location-based reminders to location-based marketing. With the increasing...
Recent advances in distributed resource-constrained systems have seen the rapid growth of interest for middleware exploitation especially in mobile cloud computing. The rapid advancement of mobile cloud computing has shown that there is a high demand for mobile cloud applications. Moreover, mobile cloud computing aims to ensure that mobile devices make the best use of cloud computing resources in...
The discovery process has become an important task in the web service life cycle as the number of Mobile Web Services (MWS) has increased nowadays. However, discovering relevant MWS that can match a service request with the service offered has remained a major hindrance. The challenges are concerning the web service discovery with the limitation of mobile devices related to performance. On the other...
This paper discusses the notion of self-organising and context-aware data flows, i.e. spatially-situated services made of flows of data propagating across mobile nodes, sensitive to their context and responding to it following self-organising principles. This paves the way for a new category of spatially-situated pervasive services based on data propagation among mobile devices.
