Electromagnetic energy harvesting is one of the most promising technologies for the future of autonomous electronic gadgets and also for making possible the globalisation of the Internet of things concept and consequently smart cities. In order to obtain an optimum dimensioning of the energy requirements in environments where a large quantity of sensors and(More)
—This paper depicts the operation of an integrated system designed for both outdoor and indoor localization, with special emphasis on the latter. It is demonstrated how three different methods of localization can be combined, based on WiFi access points and mobile cells. Not only there is no need to know the exact location of the access points to start(More)
technologies have been presented, each of them with different characteristics. Like this, the choice of the location technology is related with several important factors such as: precision, latency, power consumption, mobile nodes and infrastructure cost. Outdoor and indoor location systems provide a huge area of application, although, the integration of(More)
Outdoor location/navigation systems are a useful support for our daily life. The majority of these systems are based on Global Navigation Satellite Systems (GNSS), which include for example, Global Positioning System (GPS) and Galileo. For indoor location systems several technologies have been presented, each of them with different characteristics. Like(More)
