Performance Comparison of Scheduling Algorithms for Multimedia Traffic Over High-Rate WPANs

Abstract

In this paper we investigate the potentialities offered by IEEE 802.15.3 framework for supporting multimedia services. More specifically, we analyze the performance of some classical scheduling policies in presence of intensive heterogeneous realtime and multimedia traffic, in order to identify the most effective strategy for the considered scenarios. The analysis has been performed by using a complete 802.15.3 C++ simulator, where we have realized the different scheduling strategies upon an entirely standard-compliant round robin polling procedure. Results show that, in most cases, EDF approach offers better performance, though its margin with respect to the other strategies strictly depends on the specific scenario considered.
