Open-LTE: An Open LTE Simulator For Mobile Video Streaming

摘要

Simulation is the optimal means to evaluate the booming researches on how to enhance the end-to-end service reliability of mobile video streaming over LTE network. However, to the best of our knowledge, all existing LTE network simulators provide simulations of relatively closed virtual networks, in which only meaningless tracing data can be simulated being delivered. Researches on mobile video streaming have not yet been fully supported. In light of this, herein, the open LTE simulator Open-Sim is made to provide the simulation of virtual LTE network with the ability to connect actual hosts over real wired link in realtime. The transport and application layer related logics of video streaming can be deployed on remote hosts and will no longer be limited by the simulator framework. Open-LTE is thus compatible with experimental studies on most aspects of mobile video streaming. Open-LTE is simple to use by providing a centralized configuration file to set up the LTE channel fading scenarios and interconnect real traffic with the virtual LTE network. We will demonstrate our work with QoE experiments on a live video streaming application.
