Over the years, video applications have become the most important element of the current wireless network traffic. Although due to this notably increase, limited available bandwidth, and unstable channel conditions, make a challenging task for network operators, where a higher quality of services (QoS) that include high efficiency, wider bandwidth, and low cost need to be provided. On the other hand, provide higher quality video streaming transmitting for multi-users communication scenarios. Different parameters have been considered in various algorithms for the sake to enhance the video traffic transmit over Long Term Evolution (LTE). Investigation and evaluation of the impact of the delay jitter on LTE downlink scheduling are addressed in this work, in order to find out how much it can affect the network performance for video traffic. Even though, Delay, throughput, packet loss ratio and fairness, known as the most popular parameters, the jitter consider one of the significant parameters that affect the performance of the wireless network connection. The Jitter parameter has a significant impact on network Quality of Service (QoS) and Quality of Experience (QoE) for real-time services. Simulation results on the well-known LTE network downlink scheduling algorithms Proportional Fairness (PF), Modified Largest Delay First (MLWDF), and Exponential Rule (EXP-rule) have been evaluated. This simulation results show a significant impact for jitter parameter on video streaming transmission in LTE networks.
