Aalborg University, Aalborg, Denmark

7.1 Introduction

The concept of Internet of Things (IoT) has, since initially being coined back in 1999 by Kevin Ashton [1], been one of the driving factors behind much of the research and development within the area of wireless communication. From initially being thought of as formation of a link between the then-new idea of RFID and the then-explosively growing Internet, IoT has spawned into a very diverse range of wireless communication system scenarios. Examples of systems descending from IoT are near field communication (NFC), personal area networks (PANs), body area networks (BANs), to mention but a few. On the basis of shared characteristics many of these systems can be contained within the concept of wireless sensor networks (WSNs), as illustrated in Figure 7.1.

The WSN concept plays host to an immensely broad range of applications and the revenue forecasts estimates that the WSN market is to reach 2.0 billion USD in 2021 [2]. With all its diverse application areas WSNs are going to have a significant impact on the ICT infrastructure and how we as humans interact with ICT systems.

One of the areas where the application of WSN-based technologies is expected ...
