In this paper, a flexible bandwidth management scheme namely Bandwidth-based Polling (BBP) for Bluetooth is proposed. A framing structure of time is defined in BBP, and the master allocates proper number of slots for each active slave in a frame. Moreover, BBP allows the master to poll a slave more than once in a time frame to achieve high flexibility for bandwidth allocation. Calculation of the payload type as well as the polling time in a frame for a slave with bandwidth requirement is presented in the paper. Actions of the master and the slave for supporting BBP are also presented in the paper. Simulation results have shown that a good performance and flexibility of bandwidth allocation can be achieved by BBP.
