Abstract

By means of dynamic system-level simulations, this work evaluates whether the studied packet scheduling (PS) algorithms are capable of guaranteeing the quality of service (QoS) of the voice over IP (VoIP) on a scenario where the VoIP and Web browsing services will compete for the same resources. Two sets of algorithms were considered: QoS-differentiated and non-QoS-differentiated algorithms. It can be concluded that, in general, the PS algorithms able to perform QoS differentiation presented better performance in terms of system capacity and QoS compared to those non-QoS-differentiated algorithms. Among the former category, those that take into consideration delay requirements of the VoIP service presented the best overall capacity for all traffic mixes
