Contents I. Introduction
Development of wireless sensor networks has been driven by the need to produce a solution for the desire to obtain an increasing amount of data from a given system. Wireless systems offer a greater degree of flexibility and reduced costs compared with the inconvenience of numerous cables. In addition, transmitting the data wirelessly presents the possibility of embedding the sensors in previously inaccessible locations. However, the majority of sensor nodes are reliant on battery power. These batteries will require periodical replacement and are therefore not consistent with the concept of a fully embedded system.
