Deadline-Aware Scheduling Policies for Bluetooth Networks in Industrial Communications

One aspect to be investigated in the attempt to enhance BT support of process control traffic is the transmission scheduling algorithm used. BT scheduling does not, in fact, provide support for real-time traffic. The paper presents an approach to transmission scheduling in BT networks that not only renders scheduling deadline-aware but also enables the integrated management of all real-time traffic, both periodic and aperiodic. After describing the approach, the paper illustrates its performance, giving the results of a wide range of simulations run in various operating situations.
