QoS-based Scheduling Algorithm for LTE-A

QoS-based Scheduling Algorithm for LTE-A

The aim of this study is to propose a novel scheduling algorithm which is classified into two levels. In the first level, the users with Quality of Services (QoS) requirements, such as delay and Packet Drop Rate (PDR) which considered critical issues in wireless networks, are prioritized. In the second level, the QoS users are selected based on real-time queuing algorithm which allocates availa...

QoS AWARE MAC LAYER SCHEDULING IN LTE

A delay-aware scheduling algorithm for enhancing video services QoS in LTE system

Multimedia services are carried by data packet in LTE (Long Term Evolution, LTE) system, such as voice, video, and so on. Quality of Service in multimedia services is essential to user experience. In this paper, we present a packet scheduling algorithm to improve the performance of video traffic. By considering the number of packet loss and packet delay in the buffer, the priority of each user ...

A QoS Based Scheduling Algorithm for Continuous Media Servers

A growing set of applications require digital audio and video data, commonly referred to as continuous media (CM). These applications require continuous real{time data ow during play-back and recording. Scheduling strategies to service accesses by multiple concurrent applications at CM data servers (CMS) must provide timely access to storage devices. Besides real{time access, such data is chara...

A New Fairness Index and Novel Approach for QoS-Aware Resource Allocation in LTE Networks Based on Utility Functions

Resource allocation techniques have recently appeared as a widely recognized feature in LTE networks. Most of existing approaches in resource allocation focus on maximizing network’s utility functions. The great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (MOS) indexes has attracted large efforts over the last few years. In this p...
