A Network Simulation Tool for User Traffic Modeling and Quality of Experience Analysis in a Hybrid Access Architecture

Abstract:
A Hybrid Access Architecture, where network users can be simultaneously served by different technologies, has been envisioned in order to increase the achievable data rates and enhance the user experience. This proposed access is promising to users where the costs of replacing existing technology are unmanageable and the complementary technology is underused. In order to understand the implications of a Hybrid Access between Digital Subscriber Line (DSL) and Long Term Evolution (LTE) in Downlink (DL) operation, a Network Simulation Tool has been developed, where the services demanded by the users are defined and modeled. Additionally, the Traffic and QoE Simulator (TQoES) establishes an algorithm to select the kind of access to be used by specific services, and reliably simulates the behavior of users within an LTE network based on 3GPP recommendations.
