Wireless sensor and actor networks (WSANs) constitute an emerging and pervasive technology that is attracting increased interest for a wide range of applications. WSANs have two major requirements: coordination mechanisms for both sensor-actor and actor-actor interactions, and real-time communication to perform correct and timely actions. Additionally, the(More)
The usage of object-oriented methodologies in conjunction with formal description techniques has arisen as a promising way of dealing with the increasing complexity of embedded real-time systems. These methodologies are currently well supported by a set of tools that allow the specification, simulation and validation of the functional aspects of these(More)
We are in the presence of a new and powerful technology called wireless sensor and actor networks. There are many fields where we can apply this technology to develop varied and interesting applications: high security environments, environmental monitoring,industrial monitoring, medicine, precision agriculture. This technology brings the need to develop new(More)
Wireless sensor and actor networks (WSANs) constitute an emerging and pervasive technology that is attracting increased interest for a wide range of applications. The increasing functionality of this kind of network makes it necessary to propose tools and methodologies to facilitate software development. This paper proposes a middleware called MWSAN to(More)
Wireless Sensor and Actor Networks are potentially one of the most important technologies of this century. There are many fields where they can be used in order to develop varied and interesting applications: high security environments, environmental monitoring, objects and events detection, military surveillance and precision agriculture.

The usage of formal description techniques (FDTs) has arisen as a promising way of dealing with the increasing complexity of embedded real-time systems. However, FDTs do not take into account non-functional aspects, such as the time requirements, that are especially important in the context of this kind of system. In this paper, we present how to integrate(More)
