Heterogeneous Networks: experimental study of interference between IEEE 802.11 and IEEE 802.15.4 technologies

چکیده
Internet of Things is a key technical and economical challenge for 5G. An important number of technological solutions are developed and deployed (for instance based on the IEEE 802.15.4 standard), specially in the 2.4 GHz ISM band. However this band is shared with other communicating systems, such as WiFi and Bluetooth devices. As a consequence, dealing with interference becomes crucial and has an important impact on the energy consumption. The objective of this work is to experimentally study the nature of interference between IEEE 802.11 and IEEE 802.15.4 devices and to study its impact on the communication reliability. The MAC protocol is based on carrier sense approaches but if listening to a device using the same protocol as yourself in one thing, it can be inefficient when it comes to listening to other types of devices. Résumé: L’internet des objets est un défi technique et économique majeur pour la 5G. Diverses solutions technologiques sont développés et déployées (par exemple basées sur la norme IEEE 802.15.4), et en particulier dans la bande ISM à 2,4 GHz. Toutefois, cette bande est partagée avec d’autres systèmes communicants, comme les périphériques WiFi et Bluetooth. En conséquence, la gestion des interférences devient cruciale et a un impact important sur la consommation d’énergie. L’objectif de ce travail est d’étudier expérimentalement la nature de l’interfértence entre les dispositifs IEEE 802.11 et IEEE 802.15.4 et son impact sur la fiabilité des communications. Le protocole MAC est basé sur l’écoute de la porteuse, mais si écouter un objet utilisant un protocole identique est une chose, cela peut être inefficace quand il s’agit d’écouter d’autres types d’objets communicants.
