Resumo: Um dos aspectos centrais da Computação Ubíqua (Ubicomp) está associado a uma forte integração entre os sistemas computacionais e o meio ambiente. Um dos principais desafios da pesquisa na área é fornecer mecanismos para a consciência de contexto que promovam o desenvolvimento de aplicações que reajam de acordo com a dinâmica do ambiente de interesse do usuário. Com essa motivação foi concebido o EXEHDA-SN, um novo serviço para o middleware EXEHDA. O Middleware EXEHDA vem sendo desenvolvido para promover a execução distribuída adaptativa, a coleta e o reconhecimento do contexto, armazenamento e acesso ubíquo e comunicações assín-cronas. Nesse sentido, a principal contribuição deste artigo é a proposição do EXEHDA-SN como um serviço para o gerenciamento proativo das interações do Middleware com o ambiente físico, por meio de regras, empregando redes de sensores e atuadores. Para avaliar as funcionalidades do serviço proposto, apresentamos um estudo de caso na área agrícola, com destaque para os protótipos e testes realizados, cujos resultados se mostraram promissores.Palavras-chave: Ubicomp.

One of the main challenges of research in the area is to provide mechanisms for context-awar to promotes the development of applications that react according to the dynamics of user interest environment. With this motivation is designed the EXEHDA-SN, a new service for EXEHDA middleware. The EXEHDA Middleware has been developed to promote adaptive distributed execution, collect and recognition of context, storage and ubiquitous access and asynchronous communications. In this sense, the main contribution of this paper is the proposition of EXEHDA-SN as a service to the proactive management of the Middleware interactions with the physical environment, through rules, using sensors and actuators networks. To evaluate the functionalities of the proposed service, we present a case study in agriculture, highlighting the prototypes and tests performed. The results were promising.

IntroductionMark Weiser's classic article (Weiser, 1991), considered the precursor of Ubiquitous Computing, describes the basic assumptions of this computational paradigm: ubiquity and transparency. These assumptions generate several challenges related to user access to computing environment, anywhere, any time, with any device, non-intrusively, keeping the users' focus on their activities. In this perspective, computational systems must interact in an autonomic way, no matter where the user is, constituting a highly distributed, heterogeneous, dynamic and mobile environment (Costa et al., 2008;Caceres and Friday, 2012 Abstract. The applications in Ubiquitous Computing (UbiComp) environments must be aware of their contexts of interest and adapt to changes in them. Thus, a major research challenge in the area of UbiComp is related to context awareness. Considering the high distribution, heterogeneity, dynamism, and mobility of ubiquitous environments, this paper presents an architectural model for context awareness, called EXEHDA-UC (Execution Environment for Highly Distributed Applications -Ubiquitous Context awareness). The proposal includes elements to support contextual data acquisition, actuation in the environment, and processing of contextual information. We consider that the main contribution of this work is an architecture that supports the managing of the acquisition, storage, and processing of context data, in a distributed way, independently of the application, in an autonomic and rule-based perspective. To assess the functionalities of the EXEHDA-UC, we present a case study, highlighting the prototypes developed, technologies employed, and tests carried out.

“…HiCon [2] describes a software framework for both monitoring and composing contextual information. Given that a large collection of sensors producing sensor data in real time can overwhelm a system with a large volume of redundant and low-level data, a framework for hierarchical context monitoring and composition is proposed.…”

“…Performing context monitoring of mobile context entities in a scalable and efficient fashion is vital for smooth operation of various demanding and selforganizing systems or services. Currently, most of the related approaches monitor contexts at a fixed rate or time interval [2] [3]. At any particular instant, the 'fixed' technique may utilize more or less resources than it actually requires, as it is static in nature.…”

Presently, smart interconnected heterogeneous devices with built-in GPS, Wi-Fi, and Bluetooth capabilities are more affordable, resulting in numerous novel mobile applications. To adapt applications based on the environment they are executed in, we perform context management by proactively monitoring the (network-and location-based) context information available in such devices and applications. As this requires continuous monitoring, the common fixed data flow based technique for forwarding contexts from multiple context sensors is not energy efficient. In this paper, we propose the design and implementation of an adaptive context monitoring scheme. Alongside context awareness, we employ overlay network, agent, and policy theories. We utilize learning and personalization characteristics to make an optimized judgment of context information in an efficient and scalable fashion. This paper is complemented with protocol evaluations to validate scalability claims based on real logs.
