Abstract

With the uprising trend of the integration of wireless sensing systems in fields such as health care and industrial processes, where information exchange between power-limited devices is required, lower energy consumption and Quality of Service demands are becoming more stringent. Bluetooth LowEnergy is a promising technology that provides, besides ultra-low energy properties, compatibility with most mobile units. However,apart from power efficiency, opportune and reliable information delivery is mandatory in time-critical applications. In this paper we propose an analytical model of the delay performance of Bluetooth Low Energy for connection-oriented applications under different bit error conditions. In addition to the physical over-the-air latency, we also analyze the effect of the occurrence time of an Application Layer event on the effective transmission delay. We highlight the impact of the device’s processing speed and the timing configuration of the connectionon the final measured latency. Simulation results validate the accuracy of the model for all the analyzed cases.
