In a smart city, entire areas of infrastructure such as energy, mobility, logistics, and disposal can be linked via a universal information system. The wireless sensor networks contribute to simple information acquisition within the subsystems of the infrastructure. Operators of such subsystems receive relevant information in real time, can react in accordance with requirements, and thus save time and resources. Furthermore, the extremely energy-saving wireless networking of the sensors allows for battery-powered systems with a long service life.
In the smart city, care of those who require assistance will be revolutionized. Location-independent support will make the daily lives of people in need of long-term care, and their relatives, easier by allowing the relevant data to be transmitted anywhere via sensor networks. This will lead to an increased level of independence and better quality of life for all involved.
