Introduction to Cognitive Approaches in Wireless Sensor Networks

1.1    Introduction

Wireless sensor networks (WSNs) are constituted of small-size, lightweight, low-power nodes deployed in large numbers. They are used in a variety of applications, such as environment monitoring, health care, precision agriculture, security, food safety, water quality monitoring, intelligent transportation, smart grid communications, and so forth. Advancement in the field of low-power very-large-scale integration (VLSI) and embedded systems, together with the convergence of communication and computing technologies, has enabled the miniaturization of the sensing, processing, and communication devices. This has led to an expansion in the application domain ...
