Abstract: The pure round robin polling scheme in Bluetooth specification is inefficient in throughout and average delay. To improve the performance of the Bluetooth piconet, a new dynamic polling scheme based on memory (MBRR) is put forward. This project was enlightened by the action in which ants search for food, the efficiency of the piconet is raised by increasing the polling times to the slaves which have many more payloads. Meanwhile, this project maintains the fairness of each slave. A comparison is made in performance between PRR, ERR and MBRR schemes. The simulation result shows that the MBRR scheme excels in throughput and delay behavior, and has good fairness.

Key words: bluetooth piconet, polling, delay, throughput
