ELRR - Enhanced Limited Round Robin Mechanism Using Priority Policy Over Bluetooth Networks

Bluetooth is a wireless communication technology that provides short-range, small-size, low-cost, and low-power connectivity among mobile devices. The MAC protocol for Bluetooth is based on a Time Division Duplex (TDD) scheme, where the master determines channel access to all other slaves in the piconet. Hence, the polling scheme used by the master has a significant effect on the Bluetooth system performance. Accordingly, this paper proposes an enhanced Limited Round Robin with a priority policy for Bluetooth. In simulations, the proposed scheduling algorithm demonstrates a better overall performance in a Bluetooth network.
