Modified Scheduler for Traffic Prioritization in LTE Networks

What is it about?

LTE is widely used 4G technology, which provides simultaneously voice, data and video (with different priority) on networks. The major concept of the LTE network uses the QoS bearers technique that provides high performance in packet delivery based on prioritization of the traffic. In this paper is proposed a simulation framework for LTE technology, which realized an efficient method for QoS for LTE service classes, which reorders packets, based on classification mechanism and the associated scheduler, based on priority.

Why is it important?

Simulation’s results show that the proposed mechanism improves QoS, but the observed parameters degrade when the use of more subscribers is related to the priority implemented scheduler, in which less priority queues may not be served in the case of network overload or congestion.
