Human beings are distinguished from other creatures for
their superior capabilities of decision-making, and decision
making needs sufficient knowledge and information about the
subject and its environment. For an automated or complex
system, various sensors are applied to acquire data from
objects and their surrounding environments. Sensors are the
devices that can replace or extend human being’s physical
senses of sight, hearing, taste, smell, and touch. Application of
wireless sensor network has been proven to be more flexible
and advantageous in the domains such as home automation,
building automation, healthcare etc. A wireless sensor
network consists of spatially distributed autonomous sensors
to monitor physical or environmental conditions, such as heat,
sound, pressure, etc. and to supportively pass their data
through the network to a main location. The prevailing
networks are bi-directional, also empowering control of sensor
