Simulation for Trade-off between Interference and Performance in a Bluetooth Low Energy Network

Bluetooth Low Energy is a wireless communication protocol widely used in Internet of Things systems. As a popular protocol operating in the 2.4 GHz frequency band, it is constantly confronted with interference challenges. For instance, in a Bluetooth Low Energy network, all connections see each other as a source of interference. In this paper, the interference and reliability issues are investigated among Bluetooth Low Energy connections. The impact of various factors on the interference, such as connection parameters and network size, is shown through simulation. The trade-off between application level throughput, i.e. goodput, and reliability in a Bluetooth Low Energy network is described, which can be used in the design or deployment of Bluetooth Low Energy devices or networks.
