A Pervasive Sensor Node Architecture

A set of sensor nodes is the basic component of a sensor network. Many researchers are currently engaged in developing pervasive sensor nodes due to the great promise and potential with applications shown by various wireless remote sensor networks. This short paper describes the concept of sensor node architecture and current research activities on sensor node development at ICTCAS. 1 The Concept of Sensor Node Architecture A sensor network is made up of the following parts, namely a set of sensor nodes which are distributed in a sensor field, a sink which communicates with the task manager via Internet interfacing with users. A set of sensor nodes is the basic component of a sensor network. Many researchers are currently engaged in developing pervasive sensor nodes [1-3 ] due to the great promise and potential with applications shown by various wireless remote sensor networks [4-10]. A sensor node is composed of four basic components as shown in Fig. 1. They are a sensing unit, a processing unit, a communication unit and a power unit.
