Abstract
In the twenty-first century, the impact of wireless and ubiquitous technologies is changing the way people perceive and interact with the physical world. These communication paradigms promise to change and redefine, in a reasonably short period of time, the most common way of our everyday living. The continuous advances in the field of Wireless Sensor Networks and their direct application in Smart Spaces are clear examples of it. However, in order for this kind of new generation infrastructures to have a large-scale dissemination, there are still some open issues to tackle. In this way, this paper presents nSOM, a service-oriented framework based on sensor network design that provides internetworking services with the Internet cloud. This lightweight middleware architecture implements an agent-based virtual sensor service approach which is a compact semantic knowledge management scheme based on a dynamic composition model.

Summary
Called ubiquitous computing, is becoming more common nowadays. Through intermediate stages of objectoriented and software components engineering models, proposals intended to bring the benefits of Service-Oriented Computing (SOC) to the WSNs have begun to emerge In such manner, the SOC paradigm offers support for the development of rapid, evolvable, interoperable, and easy assembly business application processes, and where services are defined as autonomous, interoperable, and vendor-neutral entities [1, 2]. Some potential virtual sensor prototypes are focused on the transport management of goods and food, baggage control at airport boarding areas, and healthcare environments where vital signs of patients can be monitored This virtual sensor technology will allow us, with the in-network agent-based service model, to offer WSN-based services unambiguously and comprehensively in smart spaces, providing intelligent decisions that would be difficult to get when using isolated physical sensors.
