Abstract:

The constant evolution and growth of multimedia applications supported by today's mobile devices leads to an increase on the demand for video based services which impose new requirements in terms of bitrate and delay. In order to face these challenges, LTE appears as a technology capable of dealing with the video traffic load on mobile networks. However, given the inherent nature of mobile networks the devices located at the cell's edge face some difficulties when a certain SINR must be achieved. To overcome this issue, LTE Advanced comes into the picture as it makes use of Relay Nodes which were included as part of the network architecture. Based on simulations, the present work evaluates the performance of real time video applications on devices located at the cell's edge. The results show the advantage of using Relay Nodes in LTE in aspects such as the reduction of lost packets leading to an improvement of the video quality at the receiver's side.
