Gestion Dynamique Du Spectre Pour L’internet Des Objets (iot)
Résumé: The internet of things (IoT) as an evolution of the current internet allows a considerable improvement of our way of life and the way in which smart objects in our environment interact with each other and with their users. IoT is a short-range wireless network of interconnected devices, such as Wi-Fi and Zigbee. WiFi and Zigbee stand out as the preferred communication technologies for smart homes. We know that spectrum scarcity is the biggest obstacle to increasing the capacity of wireless networks. Spectrum sharing is a solution to this problem. The unlicensed ISM band is being used more and more by WLAN and WPAN users and devices. Spectrum sharing within devices on the same network is not a problem. But the coexistence of WLAN and WPAN (WiFi and Zigbee) is a difficult problem. Spectrum sharing between these networks will certainly improve the use of spectrum. Wifi and Zigbee use a 2.4 GHz ISM band. WiseBee is a spectrum management algorithm, which allows coexistence of Zigbee and WiFi by minimizing interference. It uses a single antenna receiver without modifying WiFi and ZigBee designs. Keywords Spectrum management, WiFi, Zigbee, Interference, Coexistence, IoT, WiseBee
