A Wireless Sensor Node Architecture for Exploring Distributed Sensor Network Applications

This document describes a new versatile generalpurpose wireless sensor node architecture designed around the OKI ARM ML67Q500x microprocessor and the IEEE 802.15.4 compliant CC2420 radio from Chipcon. This platform designed for experimentation, educational projects and preliminary deployment in industrial environments. The XYZ node architecture is described in the context of a 3-D testbed recently installed at ENALAB to facilitate wireless sensor experiments at scale. In the next few months, this testbed will host approximately 100 wireless devices, and it will form a flexible environment for instrumenting and testing complex sensor network scenarios prior to their deployment. The primary set of applications to be implemented on the testbed includes, node localization in 3-D space, sensor calibration and a set of controlled mobility applications such as boundary estimation.
