In this paper, the potential QoS performance improvement gained by applying application-based QoS control in wireless networks is investigated. Two important performance metrics, i.e. queuing delay and packet drop, are approximately modeled and derived for the QoS control at the base stations using a simplified queuing model. Based on it, the performance comparison between the approaches of application-based...
This study addresses the resource allocation problem for multi-user MIMO systems with consideration of real-time services. Specifically, we focused on the delay constraints modeling in this paper, since it is a fundamental QoS requirement for all real-time services. To simultaneously meet the delay constraints of all users, we first modeled this resource allocation problem with specific delay restrictions...
