Récemment, la norme IEEE 802.15.4 a été normalisée pour les WSN (Wireless Sensor Networks). Cet article propose un schéma CCA amélioré qui implique que le dispositif de transmission de données envoie un signal notifyBusyChannel (nBC) pendant la période d'attente lorsque le canal utilisant le quotient (CUQ) dépasse 0.5. Le CUQ représente le taux d'utilisation des canaux au cours de la durée du créneau précédent. Lors d'une seule opération CCA, les nœuds de périphérique sont informés de l'état occupé du canal par le signal nBC. Nous implémentons le schéma ECCA dans une puce matérielle pour une évaluation des performances. Les résultats montrent que le système proposé présente des temps d'attente courts et une consommation d'énergie inférieure à celle de la norme IEEE 802.15.4 CCA. Et le schéma est compatible avec les appareils IEEE 802.15.4 conventionnels.

Abstract: Recently, IEEE 802.15.4 has been standardized for WSNs (Wireless Sensor Networks). This paper proposes an enhanced CCA scheme which involves the data transmission device sending a notifyBusyChannel (nBC) signal in the backoff period when the Channel Using Quotient (CUQ) exceeds 0.5. The CUQ stands for the rate of channel utilization in the previous slot duration. In a single CCA operation, the device nodes are made aware of the busy status of the channel by the nBC signal. We implement the ECCA scheme in a hardware chip for a performance evaluation. The results show that the proposed scheme has short queuing times and less energy consumption than IEEE 802.15.4 CCA. And the scheme is compatible with conventional IEEE 802.15.4 devices.
