	abstract = {Innovative scheduling algorithms for packet switched air-interfaces have been shown to support higher data rates by exploiting the multiuser diversity inherent to cellular wireless systems. While such opportunistic schedulers significantly improve the system throughput, they could degrade the user experience through unfair resource allocation and increased variability in the scheduled rate and delay. The growing demand for service differentiation between real-time multimedia traffic and data traffic underscores the need for these schedulers to incorporate delay constraints. The analytical results in this paper not only highlight the inherent trade-off between system throughput and the delay experienced by mobile users with opportunistic scheduling, but they also provide a novel way of quantifying the Quality of Service(Q0S) offered by a general opportunistic scheduler.Our analysis is strongly supported by system simulations of a time-slotted cellular downlink shared by multiple mobile users with independent, time-varying channels. In addition, we use a continuous approximation to compute closed form expressions for the scheduler statistics.},

	abstract = {The integration of wireless telephony and data services in 3G and 4G wireless systems that use packet-switched air interfaces poses new challenges in the management of network resources. Although highly compressed voice traffic is given priority over data traffic, scheduling algorithms which exploit multiuser diversity have been shown to significantly improve the data throughput . In this paper, we quantify the effect of prioritized voice traffic on the performance of data users in the system using a mix of analysis and simulation. We analytically characterize the scheduled rate, delay and packet service times for data in the presence of prioritized voice traffic by using a general scheduling metric that incorporates a measure of the user{\textquoteright}s channel quality in addition to a delay constraint. The results provide important tools for cellular network operators to evaluate system performance and provision resources for traffic with varying Quality of Service(QoS) requirements.},
