Avaliação do consumo energético do Bluetooth Mesh

Abstract

This work proposes a Clustering Algorithm based on LEACH to improve the energy efficiency of Bluetooth Mesh networks. To further reduce the burden over the Cluster Heads, an Radio Duty Cycling algorithm that requires no modification in the current Bluetooth Mesh Profile is needed, only a simple modification on the packet transmission logic. Computer simulations shows that the proposed radio duty cycling and clustering methods for reducing idle listening are very effective in improving energy efficiency. It was observed that duty cycling brings up to 90% of improvement in energy efficiency. In addittion, simulations shows that the proposed clustering technique is effective in controlling the excessive message replication that is inherent in flooding operation, which in turn have a positive impact on packet delivery ratio and network scalability. Finally, it can be observed that the proposed clustering algorithm, when applied with the proposed radio duty cycling algorithm can provide an improvement in energy efficiency when compared to the baseline Bluetooth Mesh profile.
