Mobile computing applications are required to operate in environments in which the availability for resources and services may change significantly during system operation. As a result, mobile computing applications need...

Neste artigo, propoe-se um algoritmo para reconfiguração dinamica de aplicac;oes distribuídas implementadas de acordo com o modelo de agentes móveis. Mostra-se também que este algoritmo pode ser facilmente implement...

This paper presents an architecture for the development of software for smartphones. It explains the advantages of web application development with respect to native applications - those installed on mobile devices that ...

"GPS and location services have been a breakthrough in recent history and have become a necessary part of our daily lives, but they haven't yet reached the point where we can be located inside buildings. This would be re...

Este artigo propõe recursos para o escalonamento de objetos distribuídos. Para tanto, são definidos dois mecanismos tidos como centrais para tal: um primeiro que irá realizar a instanciação remota de objetos Java, ...

Ad hoc wireless networks have become the architecture of choice for peer to peer communications in areas where the telecommunications infrastructure is inadequate or has failed. A major challenge is the reliable delivery...

Diversas propostas estão sendo implementadas para reduzir os problemas do gerenciamento da mobilidade em redes sem fio. O protocolo Mobile IP é o padrão utilizado atualmente na Internet, fornecendo uma solução globa...

The interaction between software systems by means of mobile code is a powerful and truly effective method, particularly useful for installing and executing code dynamically. However, for this mechanism to be applicable s...

The great advance of the communications and the importance gained by the mobile systems have increased the development of WAP (Wireless Application Protocol) applications, nevertheless at the present time do not exist me...

The publication of Mobile IPv6 RFC 3775 by the IETF is a breakthrough in the data communications industry to achieve the technology convergence required by ubiquitous mobile devices. MIPv6 not only brings the possibility...

This paper shows a modeling and developing methodology for mobile web applications using the MDA (Model Driver Architecture) approach. It´s based on a conservative extension of UML allowing modeling with any existing to...

This paper presents a basic and an extended heuristic to distribute operating system (OS) services over mobile ad hoc networks. The heuristics are inspired by the foraging behavior of ants and are used within our NanoOS...

Remote interaction with immersive 3D environments with acceptable level of quality of experience has become a challenging and interesting research topic. Due to the high data volume required to provide a rich experience ...

Las redes móviles están en pleno auge desde no hace más de una década. Están compuestas por dispositivos que no siempre poseen conexión con la red. Sobre los dispositivos pueden correr aplicaciones que, en caso de ...

A wireless ad hoc network is a collection of wireless nodes that can dynamically self-organize into an arbitrary and temporary topology to form a network without necessarily using any pre-existing infrastructure. These c...

CSCW is a well-suited discipline for appropriate communicating ideas inside a group and even in an inter-group cooperation. Though basic technology for communication annoy people with too many computer-related tasks to d...

Because of the remote nature and the size of sensor nodes, they rely on limited battery energy that cannot be replenished in many applications. Thus, low power consumption technology is a major issue in wireless sensor n...

Wireless Technologies have allowed a fast growing of the Internet service in both public and private environments where wireless networks mostly consist of nodes interconnected with a fixed infrastruc- ture; nevertheless...

Most of the current wireless sensor networks are built for specific applications, with a tight coupling between them and the underlying communication protocols. We present a more flexible architectural approach for build...

Con la proliferación de la computación móvil, la habilidad de indexar eficientemente los movimientos de los objetos móviles es cada vez más importante. Actualmente, variadas aplicaciones utilizan bases de datos que ...

mTagATune is a mobile game based on TagATune. mTagATune implements the concept of GWAP and seizes the capabilities and wide acceptance of current smartphones. GWAP promotes the creation of computer games that encourage ...

The Unified Modeling Language (UML) is a language for visualizing, specifying, constructing, and documenting the artifacts of a software-intensive system. UML supports the most typical software modeling problems; however...

En la actualidad, existe un considerable número de aplicaciones que permiten realizar búsquedas en bases de datos cuyo criterio es especificado mediante una imagen, en lugar de la tradicional utilización de palabras c...

Esta línea de investigación busca crear una metodología de modelado utilizando una extensión conservativa de UML (Lenguaje Unificado de Modelado) que permita diseñar aplicaciones web móviles centrándose en el mode...
