People worldwide are getting older and this fact has pushed the need for designing new, more pervasive, and possibly cost effective healthcare systems. In this field, distributed and networked embedded systems, such as wireless sensor networks (WSNs), are the most appealing technology to achieve continuous monitoring of aged people for their own safety,(More)
In this paper, we analyze and describe the achievable performance of a Wireless Sensor Network (WSN) testbed platform, which has been deployed at the Center of Excellence DEWS (University of L'Aquila, Italy) for positioning applications, and which is implemented using CC2431 sensor nodes developed by Texas Instruments® (TI)/Chipcon. In particular, we(More)
We consider reliable communications in Body Area Networks (BAN), where a set of nodes placed on human body are connected using wireless links. In order to keep the Specific Absorption Rate (SAR) as low as possible for health safety reasons, these networks operate in low transmit power regime, which however, is known to be error prone. It has been observed(More)
SUMMARY This paper describes a new industrial case on automation, for large-scale systems with high environmental impact: the mining ventilation control systems. Ventilation control is essential for the operation of a mine in terms of safety (CO and NO x regulation) and energy optimization. We first discuss a novel regulation architecture, highlighting the(More)
—The IEEE 802.15.4 standard has been attracting strong interest, but in the academic community so far very little research related to the IEEE 802.15.4 MAC has been evaluated experimentally, with real hardware under realistic conditions. This is mainly due to the fact that a stable, open-source IEEE 802.15.4 MAC implementation has been unavailable for a(More)
In the new era of connectivity, marked by the explosive number of wireless electronic devices and the need for smart and pervasive applications, Machine-to-Machine (M2M) communications are an emerging technology that enables the seamless device interconnection without the need of human interaction. The use of M2M technology can bring to life a wide range of(More)
Life expectancy is projected to increase significantly in the coming years. This fact has pushed the need for designing new and more pervasive healthcare systems. In this field, distributed and networked embedded systems, such as Wireless Sensor Networks (WSNs), are the most suitable technology to achieve continuous monitoring of aged people for their own(More)
Nowadays, one of the most representative and vibrant examples of networked embedded systems is represented by Wireless Sensor Networks (WSNs). For many WSNs applications, it is well-known that the determination of the node's location is of prime importance. Moreover, for WSNs the most popular solution for localization, i.e., the GPS-aided (Global(More)
