Node-Level Optimization of Wireless Sensor Networks

A methodology for WSN planning should produce a suitable placement of sensors to simplify the acquisition of the data relevant for the application. The goal of this paper is to present a strategy to formally specify the system level characteristics of the events to be monitored and to identify a proper set of sensor-position pairs, tailored to provide the required sensing capabilities. In particular the focus is on the node level optimization, where the designer has to face with the problem of clustering sensors onto the same board based upon a cost-performance tradeoff.
