Over the past decades, the miniaturisation and cost reduction brought about by the semiconductor industry have made it possible to create computers that are smaller in size than a pin head, powerful enough to carry out the processing required, and affordable enough to be considered disposable. This reduction in size and increase in processing capability will undoubtedly continue in future years, with new classes of computer or smart device emerging in every decade (Bell G, Commun ACM 51(1):86–94, 2008). Similarly, advances in wireless communication, sensor design, and energy storage technologies have meant that the concept of a truly pervasive Wireless Sensor Network (WSN) is rapidly becoming a reality (Bulusu N, Jha S, Wireless sensor network systems: a systems perspective. Artech House Publishers, 2005). Integrated microsensors no more than a few millimetres in size, with onboard processing and wireless data transfer capability are the basic components of such networks already in existence nearly a decade ago (Warneke et al, Computer 34(1):44–51, 2001; Kahn et al, Next century challenges: mobile networking for smart dust. In: Proceedings of the international conference on mobile computing and networking, Boston, MA, 2000). With rapid expansion of smart devices in recent years, many applications have been proposed for the use of WSNs and they are likely to change every aspect of our daily lives.
