The tremendous developments that continue to evolve in the field of information
communication technology (ICT) are affecting nearly all aspects of human lives. Mobile
phones currently support many applications and deliver services that go well beyond basic
voice communication. Wireless sensor networks with ubiquitous embedded processors can
sense various parameters and generate the appropriate responses. These are some examples
of systems that are being driven by advancements in ICT. Another important ICT driven
field is the smart home. This field has been the subject of concerted research effort for some
time and is beginning to develop practical products for a market that is expected to grow
substantially in the relatively near future
