Developing and evolving critical information systems in order to cope with changes in regulations and laws is a constant worry for governments in the e-Government era. Due to the frequent challenges and some previous frustrating experiences, the Brazilian Government has searched for an alternative development method that could better fit its needs. At the same time, Brazilian Academia, represented...
Web application development benefits massively from modular architectures and reuse. This excellent software engineering practice is also the source of a new form of monoculture in application-level code, which creates a potential risk for dependability. Researchers propose using software diversification in multiple components of Web applications to reconcile the tension between reuse and dependability...
Billions of smart devices will be connected to the Internet to form the Internet of Things. The core value of IoT (Internet of Things) is to supply information services through the huge amounts of devices. Most of sensors, actors and terminal equipment such as mobile phones are resource-constrained in battery, bandwidth, storage and computation ability. Accordingly, we propose an information service...
Despite research spanning more than a decade in the area of Web services, the industry has not yet seen a consensus regarding an effective method for the provisioning of Web services. In recent years, a new paradigm for implementing Web services based on Representational State Transfer, the successful architectural foundation of the Web, has seen greater interest in the industry. We had previously...
In order to find solutions for merging heterogeneities among various home networks, we proposed an approach to develop an unified Service-Oriented design pattern to build a network controller and service platform, and implement the home service bus with loosely-coupled systems, to make smart appliances become easier to build upon. We detailed the multilayer architecture of our system and its implementation,...
Academic Information is very important for college students and should be conveyed to all students equally. But as is well known that a lot of students make the staff of college cannot convey information in a personal one by one on each student. In order to support good communication, synchronized, and quick to students. College facilitates through conventional media announcement. Academic Information...
The cases of infections, hospitalizations and deaths from dengue in the world represent a scenario that involves a series of public policy. Among the hosts of the disease tropical countries, Brazil stands out with high levels of potentially alarming cases, mainly due to its environmental and social conditions favorable to the proliferation of the mosquito Aedes Aegypti. Given scenario, this paper...
Smart homes are driven by heterogeneity in nature and consist of diverse components that promote user comfort and security. In recent times, tremendous growth of Internet of Things (IoTs) applications is seen in smart homes. The huge diversity of various IoTs applications generally leads to interoperability requirements that need to be fulfilled. Current IoTs management is achieved using physical...
Cloud architecture has the ability of sharing hardware resources and services among multiple tenants. In this paper we measure the performance for the multi-VM (multiple virtual machines) cloud architecture and compare it with the single-VM architecture. Renting resources on a cloud usually comes with a variety of options, such as use of more and smaller virtual machines or use of less and bigger...
Cloud service providers offer their customers to rent or release hardware resources (CPU, RAM, HDD), which are isolated in virtual machine instances, on demand. Increased load on customer applications or web services require more resources than a physical server can supply, which enforces the cloud provider to implement some load balancing technique in order to scatter the load among several virtual...
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...
Augmented reality (AR) is a promising technology for building applications in an Internet of Things (IoT) environment, utilized for visualizing information provided by IoT devices. In this paper, we enable Web-based mobile AR applications with mobile agents in a resource-oriented IoT system architecture. We present an adaptable mobile agent composition that contains the data representation logic and...
With the rapid development of computer technology and network transmission technology, more and more demand are put forward to improve the work efficiency, which are not limited to just use computers and laptops. In most institute of Measurement, too many instrument transfer process seriously restricted the work efficiency, how to solve the problem with smart mobile terminal has become a common topic...
Due to advances in wireless network technology, new applications are designed in medical and health care domain. Medical personnel efficiency has increased by using these new tools and applications. Patient of young and elderly people as well as smart houses equipped with sensors and information technologies are subject to discussion. Patients wear sensors to monitor vital signs reported in real-time...
In this article we present a 3-layer architecture (MAPIS3) that facilitates the flexible implementation of technology-enhanced collaboration scripts. The proposed architecture introduces a mediator component (MC) as a key element for orchestrating and controlling data flow among tools. These tools can also include external services necessary for script implementation (e.g. a forum or chat, etc.)....
Internet of Things (IoT) envisions connecting and managing billions of devices and endpoints. This paper describes a smart M2M gateway based architecture to manage the huge volume of M2M devices and endpoints. The architecture is compliant with both ETSI and one M2M standards recommendations. The resources and the attributes of the M2M devices and endpoints are described using CoRE Link Format. The...
As computing becomes ubiquitous, researchers and engineers aim to exploit the potential of the pervasive systems in order to introduce new types of services and address inveterate and emerging problems. This process will, eventually, lead us to the era of urban computing and the Internet of Things; the ultimate goal being to improve our quality of life. But these concepts typically require direct...
Autonomic computing seeks to render computing systems as self-managed. In other words, its objective is to enable computer systems to manage themselves so as to minimise the need for human input. Software architectures can be used in order to express constraints to be maintained all along the execution of a system and, conversely, to present the state of the running system. In this paper, we present...
Online services are no longer isolated. The release of public APIs and technologies such as web hooks are allowing users and developers to access their information easily. Intelligent agents could use this information to provide a better user experience across services, connecting services with smart automatic behaviours or actions. However, agent platforms are not prepared to easily add external...
The growing number of services available within social applications (viz. Social networks) raises a new and challenging search issue: selecting desired services from social networks. Traditional discovery and selection approaches, which are registry-based (e.g., UDDI, ebXML), have manifested their limitations as they often fall behind users' expectations. This is because registries fail to (i) take...
