Abstract

In this paper a MAC level Link Adaptation (LA) strategy to be implemented in a Bluetooth piconet is investigated: the performance level that can be achieved in terms of throughput is derived and the comparison with the case of no LA is performed.Suitable definitions of the performance figures related to throughput are given and, starting from the knowledge of the physical level performance obtained via simulation, their analytical evaluation is performed in both the cases of LA and no LA.All aspects related to the propagation characteristics of the environment, the modulation/demodulation and coding/decoding techniques, and the multiple access strategy are taken into account in an integrated way; moreover a reference scenario analytically characterized along with a realistic scenario have been considered for the performance level assessment.The analytical results have been compared with simulation outcomes which confirm the validity of the approach adopted.
