ABSTRACT

This chapter provides a brief overview of the wireless sensor network area, by introducing the building concepts to the reader. The number of applications as well as possible typical scenarios will be presented to better understand the field of application of this new emerging technology. The wireless sensor networks is the generic name under which a broad range of devices hide. Basically, any collection of devices equipped with a processor, having sensing and communication capabilities and being able to organize themselves into a network created in an ad hoc manner falls into this category. A lot of effort has been invested in studying all possible aspects of wireless sensor networks. The wireless sensor networks may consist of thousands of devices working together. The algorithms for the wireless sensor networks have as one of their characteristic the fact that they do not require a predefined well–known topology.
