Since in most wireless sensor network (WSN) scenarios nodes must operate autonomously for months or years, power management of the radio (usually consuming the largest amount of node's energy) is crucial. In particular, reducing the power consumption during listening plays a fundamental role in the whole energy balance of a sensor node, since shutting down(More)
Wireless sensor networks (WSNs) have received significant attention in recent years and have found a wide range of applications, including structural and environmental monitoring, mobile health, home automation, Internet of Things, and others. As these systems are generally battery operated, major research efforts focus on reducing power consumption,(More)
In video surveillance there is an ever-growing demand for heavily distributed radio cooperating objects that Wireless Sensor Networks (WSNs) can satisfy. We present a preliminary study of an energy efficient multimodal WVSN using a main node deciding which camera to trigger based on the information from a Pyroelectric InfraRed (PIR) network. The evaluation(More)
Air quality monitoring in indoor environments is of great significance for comfort and health, especially nowadays that people spend more than 80% of the day indoor. We propose a flexible wireless system able to detect polluted air and dangerous situations in a complex and large environment. It is important for ambient intelligent systems to be unobtrusive(More)
Development of radio telemetry enabled long-term monitoring of hard-to-reach and harsh environments. This paper compares two WSN deployment projects for gathering sensor data in glacier monitoring application — GlacsWeb and PermaSense, in terms of system design and wireless communication. We discuss the potential benefits of energy-efficient event detection(More)
Metal-Oxide Semiconductor gas sensors are small in size and affordable, which makes them appropriate for implementation in battery-powered wearable sensing devices. However, their big flaw is the need to be heated to a certain temperature to react with the gas from the atmosphere, which consumes energy and drains the battery of the sensing device. In this(More)
