Abstract
In order to address the pressing needs for energy efficiency, system stability, and reliable data transmission in medical Internet of Things (IoT) applications, a novel routing algorithm built upon Bluetooth Low Energy (BLE) mesh network architecture is proposed. This proposed algorithm quantifies the channel quality for each communication link within the network. By doing so, it retains only the two most viable links between the source and destination nodes to guarantee stability in message transmission. Moreover, the algorithm minimizes the number of solitary nodes functioning as intermediaries. This mitigates the risk of node over-utilization, which is a common cause of rapid battery depletion, thus prolonging the overall lifespan of the network. Comparative experimental data indicate that this proposed algorithm outperforms conventional mesh networking approaches in both channel quality and energy sustainability.
