Enhancing bandwidth utilization in Bluetooth using optimal SAR
Ashish K. Agarwal, Chinmoy Dutta, Dheeraj Sanghi · 2002
This paper focusses on Segmentation and Reassembly (SAR) policies in Bluetooth. Bluetooth baseband packets are small and have large overheads. This makes the optimal size decision for packet size very important. This decision is further complicated by slot reservations for SCO connections and scheduling decisions. The goal of any policy is to provide maximum possible slot utilization and throughput keeping in mind the availability of data at the master and slaves. In this paper, we study two existing SAR policies - Best Fit and Optimum Slot Utilization. We show that each of them may perform poorly in some cases. We propose a new SAR policy, which we call Optimal SAR and present simulation results to show that it performs better than the other two.
