Autonomous Under Water Sensor Networks UWSNs form distributed amorphous computing environments. This emerging technology will pay off the need of conventional large, expensive, individual Ocean monitoring equipment. Efficient resolution for an unreachable UWSN which includes failureprone nodes will require strategies that are as simple as possible in computations and local communications, to fa...

This works describes the system LAURA which provides patient localization, tracking and monitoring services within nursing institutes through a wireless sensor network. The system is composed of three functional blocks: a localization and tracking engine which performs localization out of samples of the received signal strength and tracking through a particle filter; a personal monitoring modul...

Reconfigurable intelligent surfaces (RISs) are a recent yet revolutionary development in communications systems. Particularly applicable to millileter wave (mmWave) systems, these can increase localization performance and decrease vulnerability environmental influences, all by adjusting the incoming signals’ phase. At same time, manufacturing ideal hardware be deployed at transceivers is not fe...

Imagine a tracking agent P who wants to follow a moving target Q in d-dimensional Euclidean space. The tracker has access to a noisy location sensor that reports an estimate Q̃(t) of the target’s true location Q(t) at time t, where ||Q(t)−Q̃(t)|| represents the sensor’s localization error. We study the limits of tracking performance under this kind of sensing imprecision. In particular, we invest...
