Hugo de guy Professor Katholieke Universiteit Leuven Senior study Fellow IMEC The regular evolution of undefined, software program and communications know-how is quickly reworking the computer- and dot.com global into the realm of Ambient Intelligence (AmI). This subsequent wave of data expertise is fundam- tally various in that it makes disbursed stressed out and instant computing and verbal exchange disappear to the heritage and places clients to the foreground. AmI adapts to humans rather than the wrong way round. it is going to increase our attention, visual display unit our overall healthiness and safeguard, advisor us via site visitors and so forth. briefly, its final objective is to enhance the standard of our lifestyles via a quiet, trustworthy and safe interplay with our social and fabric surroundings. What makes AmI engineering so attention-grabbing is that its layout begins from learning individual to global interactions that have to be carried out as an int- ligent and independent interaction of just about all beneficial networked digital intelligence at the globe. it is a new and intriguing measurement for many select- cal and software program engineers and will allure extra artistic expertise to engineering than natural know-how does. improvement of the top know-how for AmI will basically be triumphant if the engineering examine neighborhood is ready to hitch forces in an effort to make Mark Weiser’s dream of 1991 come real. this may now not be company as ordinary by way of simply doubling transistor count number or clock velocity in a microprocessor or expanding the bandwidth of communication.

It can be thought of as a sort of platform-based design‚ where a highly parallel architectural template and a set pre-characterized hardware components drastically simplify the way to layout. Our vision of future wireless sensors does not rule out the current efforts towards sensors with high computational power. The target for this type of sensors will be closer to what can be done today with commercial sensors‚ such as interactive buildings or environmental control. The node’s intelligence‚ for instance‚ could be used to provide compatibility with different communication protocol standards.
Finally‚ the power supply section provides energy for all other units. The power breakdown over the three sections is heavily affected by their implementation. While the sensor/ADC has limited implementation flexibility‚ the wireless interface and the computational units offer several alternatives. Intuitively‚ if the wireless interface is realized using RF communication‚ it would definitely be the largest contributor‚ possibly exceeding the whole power budget alone. For this reason‚ optical‚ laser-based communication should be preferred; to give a rough idea‚ a RF-based communication has a transmission efficiency around whereas laser-based communication is around 1 nJ/bit .
This constraint translates into the adoption of more efficient architectures that allow to put most functionalities on a single chip. In particular‚ at least the MAC and the baseband processing should be implemented in a single-chip. In some cases‚ even the transceiver section can be implemented in CMOS technology and integrated onto the same chip. Fewer components translate into reduced billof-materials required for a multi-mode implementation of the device‚ and cost is reduced as a consequence.
