We focus on designing networks of wireless sensors to perform distributed sampling and interpolation. Sensors periodically sample a physical quantity of interest and report their measurements to a data center. A spatially continuous estimate of the quantity can then be constructed through interpolation. `Design' involves deciding upon how many sensors are needed and where exactly to deploy them. The...
Access to Wireless Sensor Networks (WSNs) from external applications will become a key aspect in order to successfully deploy this technology. This paper presents the Light-Weight Exterior Sensornet Protocol (LWESP), to enable the communication between applications and WSNs. This protocol is a combination of the Sensor Communication Language (SENCOMLNG) and the eXtensible Binary Enconding (XBE32)...
This paper concerns the problem of estimating a spatially distributed, time-varying random field from noisy measurements collected by a wireless sensor network. When the field dynamics are described by a linear, lumped-parameter model, the classical solution is the Kalman-Bucy filter (KBF). Bandwidth and energy constraints can make it impractical to use all sensors to estimate the field at specific...
