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...
The traditional techniques developed to deal with the issues in business process improvement don't meet the current and future organizations requirements. The existing methods are technology/fixed business process centric and not user-centric. The systems that can recognize the context of the user can bring great benefits especially enabling businesses to run more efficiently from any location. In...
Mobile devices like PDAs or mobile phones have become widespread. Similarly network functionality like GSM, Bluetooth or WLAN has become a standard. Nevertheless, not many applications take mobility into account. An application and its communication component are tightly coupled and the application assumes that network behavior does not change. Here in this paper we propose a new lightweight architecture...
Situation awareness is a promising approach to recommend to a mobile user the most suitable resources for a specific situation. However, determining the correct user situation is not a simple task since users have different habits that may affect the way in which the situations arise. Thus, an appropriate tuning aimed at adapting the situation recognizer to the specific user is desirable to make a...
Tourism sciences represent a very active research field in Computer Science today. In particular, in the realm of ubiquitous computing. The evolution of mobile devices and their proliferation in society, the advancement of communication technologies and the trend toward creating hybrid spaces (symbiosis between nature and technology) will trigger a radical change in the way persons involved in mobility,...
We present an effective power reduction scheme for recent mobile devices, e.g., Android devices, which tend to have problems with battery life because some of their applications may be running continuous sensor operations. We propose a context-aware method to determine the minimum set of resources (processor cores and peripherals) that results in meeting a given level of performance. With it, unnecessary...
In order to make mobile devices get Web Services continuity and stability, we propose a method called lazy strategy for efficient utilizing Web Services, which used as computing strategy when we encounter avalanche of expressions in runtime. Both the conception and technology as we known are just like an introduction or elimination approach that it solves the space explosion problem by type checking...
In developing countries, mobile devices can play an important role in delivering learning. But, poor information infrastructure and higher costs of mobile devices and connectivity restrict possibilities of providing successful mobile learning services. In the field of Information Communication for Development (ICT4D), this research aims to highlight the possible role of previously unexplored open...
The increasing processing power, storage and support of multiple network interfaces are promising the mobile devices to host services and participate in service discovery network. A few efforts have been taken to facilitate provisioning mobile Web services. However they have not addressed the issue about how to host heavy-duty services on mobile devices with limited computing resources in terms of...
Numerous advances in the area of ubiquitous computing resulted in appearance of such paradigms as Smart Spaces, where a number of devices can use a shared view of resources and services. Nowadays we observing emerge of the smart space technologies, which are truly mobile and allowing equally efficient design of applications for the broad range of devices. An example of such smart spaces platform is...
Looking for optimizing the battery consumption is an open issue, and we think it is feasible if we analyze the battery consumption behavior of a typical context-aware application to reduce context-aware operations at runtime. This analysis is based on different context sensors configurations. Actually existing context-aware approaches are mainly based on collecting and sending context data to external...
Mobile devices that are capable of playing Internet videos have become wide-spread in recent years. Because of the enormous offer of video content, the lack of sufficient presentation space on the screen, and the laborious navigation on mobile devices, the video consumption process becomes more complicated for the end-user. To handle this problem, people need new instruments to assist with the hunting,...
The vertiginous penetration and advance of mobile devices in all levels of our society leads towards new technological challenges. This paper is focused on the application of mobile devices in the learning environment, since the current mobile learning development is finding several problems and lacks, such as use of the new features (e.g. location and motion sensors) and the desigh without having...
In this paper, we present a novel method for image annotation and retrieval on mobile device by using contextual information. Image annotation is an effective way for content based image retrieval. However, manual annotation is an expensive and time consuming work, especially for mobile device. Here, we propose a semi-automatic way to give image annotation on mobile device. There are rich contexts...
In this paper, we target the problem of the situation-aware application (task) recommendation on mobile devices. To tackle this problem, we develop both supervised and unsupervised approaches. We use Naive Bayesian as a supervised approach, and co-clustering and vector quantization (VQ) as unsupervised approaches. We evaluate the performance of the proposed approaches with both synthetic and actual...
Mobile device can be used as a medium to send and receive the mobile Internet content. However, there are several limitations using mobile Internet. Content personalisation has been viewed as an important area when using mobile Internet. In order for personalisation to be successful, understanding the user is important. In this paper, we explore the implementation of the user profile at client-side,...
In this paper, we describe the design and implementation of a location and situation based pervasive mobile adventure game named Sportix. The prototype uses different kinds of sensor data - including 3D acceleration data and XPS - to determine the current position and activity of the player. Depending on the firm classification, data and quests are retrieved accordingly from a central information...
Mobile learning is transforming the way of tradition education. But most of e-learning system and contents are not suitable for mobile device. In order to provide suitable mobile learning services, the approach for self-adaptation is proposed in this paper. Firstly, the formal definitions of context and its influence on learning service, including NCxt, side S, weighing Q and adaptation coefficient...
Pervasive computing environments (PCE) derive the emergence of new pervasive application ranging from home to healthcare domain. These applications can be accessed from any place; at any time from anyone as in PCE users are mobile and may use mobile devices in accessing the resources and services. Thus controlling access to resource/services is a concern security question in PCE. Researchers have...
The pervasive computing world in which the context-aware applications are aimed at is constituted of multiple network environments, e.g. ad hoc, mobile and fixed. There exist specialized Context Management Systems (CMSs) addressing context management needs of every network environment and the existence of a single CMS catering all the network environments does not seem to be plausible. Placing CMS...
