Adaptive Bandwidth Allocation in an 802.15.3 Master-Slave Bridge

We investigate the performance of two IEEE 802.15.3 piconets, interconnected in a parent-child manner, and linked through a bridge device which operates in a master-slave fashion. We have designed an adaptive bandwidth allocation algorithm for bridge down link CTA allocation, and examined the impact of the value of the smoothing constant and threshold hysteresis on the throughput, blocking probability, and average queue size for the downlink queue at the bridge.
