In this paper two Service Specific Queue Sorting Algorithms (SSSA) are proposed for Real Time (RT) and Non Real Time (NRT) streaming video traffic, respectively. The proposed SSSA is implemented in a QoS aware dynamic Packet Scheduling Architecture (PSA) for Long Term Evolution-Advanced (LTE-A) networks and aims at improving the support of QoS guarantee and maintaining the overall system throughput and user fairness at a good level. Multiuser diversity is exploited both in the Time Domain (TD) and Frequency Domain (FD) to achieve effective resource utilization. The simulation results show that SSSA has reduces average delay, delay viability and Packet Drop rate (PDR) of RT traffic and fulfils throughput requirements of NRT streaming video traffic while keeping the system overall throughput and fairness among users at a good level.
