Abstract:
Information processing is applied everywhere in our time from smart medical care to intelligent cities, from households to mass production. To improve the overall performance of these systems, referred to as cyber-physical systems, distributed system architectures with intelligent nodes providing information pre-processing and data merging are applied. Only mobile devices can be used which cannot be recharged, therefore, the ultra-low power consumption is a must. Data transfer has to be solved by wireless communications and the radio devices have to operate in severe multipath mobile environments. According to the expectations, these devices have to operate for many years without any maintenance and battery replacement. The ultra-low power consumption implies that the algorithms used can be implemented only on resource-limited computing platforms and that only simple communications technologies can be applied.
Today the main trend in ICT research is to improve the data throughput, reduce latency time, etc. To achieve these goals more and more sophisticated algorithms are introduced but, unfortunately, those algorithms are extremely power-hungry.
In the special applications considered by the EFOP Workshop only a very limited amount of data has to be processed, even more, many times a relatively long latency time can be tolerated. However, the ultra-low power consumption is a must. The EFOP Workshop will survey those brand new emerging signal processing methods, communications technologies and implementation tools which can help to achieve the finite goal, the ultra-low power consumption.
