“…In previous references, in the scenario where one command controls a device, PDR was defined as the ratio of the number of data packets received by the destination node (RX Packet to DST) to the number of data packets sent out by the source node (TX Packet from SRC), usually expressed as a percentage. 2) RTT [14,15] as the abbreviation for "Round Trip Time": it represents the time it takes for a message to be transmitted in a mesh network. In previous references, in the scenario where one command controls a device, RTT was defined as the total time it takes for a message to be sent from the source node to the destination node and then returned back to the source node.…”

“…For Bluetooth Mesh networks, PDR (Packet Delivery Ratio) is still an important evaluation metric for measuring network stability. Previous references have used PDR to describe the success rate of controlling a single device in a Bluetooth Mesh network [13][14][15]. However, this article uses PDR to specifically refer to the success rate of controlling a group consisting of multiple devices.…”

Although the Bluetooth Mesh protocol is still being improved, it has found widespread use in industries such as smart homes. One major challenge faced by this protocol is how to handle problems caused by broadcast storms. It is commonly believed that a Bluetooth Mesh network with a large number of devices can easily trigger storms, which directly impact the success rate and latency of message transmission within the network. The primary purpose of this article is to quantitatively analyze the impact of broadcast storms in mesh networks. To achieve this goal, we define typical application scenarios, propose new measurement metrics, and design an experimental system. After analyzing the experimental results, we have determined that under reasonable improvements, the impact of broadcast storms on mesh message control success rate should not be overstated. Additionally, we have identified a quantitative relationship between experimental results and broadcast storms. Finally, based on these experimental findings and extensive user feedback, we provide several suggestions for improving Bluetooth Mesh networks.
