In this paper, we introduce a new medium access control (MAC) protocol for event-driven wireless sensor networks (WSN). Generally, there are three models of WSN: continuous, on-demand and event-driven. They have different characteristics and each requires a different design model. In the event-driven WSN, the sensors send data only when certain events occur. Normally, the sensors do not have mu...

Event-driven programming divides a program’s logical control flow into a series of callback functions, making its behavior difficult to follow. However, current program analysis techniques can preserve the event model while making event-driven code easier to read, write, debug and maintain. We designed the Explicit Event Library (libeel) to be amenable to program analysis, and created tools to ...

VigilAgent is a methodology for the development of agent-oriented monitoring applications that uses agents as the key abstraction elements of the involved models. It has not been developed from scratch, but it reuses fragments from Prometheus andion elements of the involved models. It has not been developed from scratch, but it reuses fragments from Prometheus and INGENIAS methodologies for mod...

LANSF is a software package that was originally designed as a tool to investigate the behaviour of medium access control (MAC) level protocols. These protocols form an interesting class of distributed computations: timing of events is the key factor in them. The protocol definition language of LANSF is based on C, and protocols are specified (programmed) as collections of communicating, interru...

The scope and responsibilities of control applications are increasing due to, for example, the emergence of industrial internet. To meet the challenge, model-driven development techniques have been in active research in the application domain. Simulations that have been traditionally used in the domain, however, have not yet been sufficiently integrated to model-driven control application devel...

This paper presents a robust fractional order controller for flexible-joint electrically driven robots under imperfect transformation of control space. The proposed approach is free from manipulator dynamics, thus free from problems associated with torque control strategy in the design and implementation. As a result, the proposed controller is simple, fast response and superior to the torque c...

The objective of spatially-aware access control models is to regulate the access to protected objects based on position information. In that last years, increasing attention has been paid to spatiallyaware access control models for mobile and pervasive applications. Following the experience of design of the GEO-RBAC model, in this paper we want to look at those models with a critical eye and po...
