Multiservice Heavy Traffic Performance of Small Cells

Abstract

The Fifth generation of wireless networks will bring, among other benefits, a revolution on the performance of mobile telecommunications services, allowing new applications, some with very stringent quality of service requirements, such as, drones, robotics, industrial control processes, smart grid distribution automation, driving support systems, autonomous cars, but others with a moderate accepted response like enhanced mobile broadband, high mobility cases (planes, trains, etc.), smart cities etc. The goal of this paper is to present a study of the performance reaction of selected parameters, in a wireless cell environment with fixed capacity, under multiservice intense traffic variation, by means of simulation experiments, including mass communications events of unexpected traffic growth. Although motivated by a research on how tight such parameters should be in a Fifth generation environment, the present study applies also to former networks generations, providing a framework of practical measures to handle a growing traffic close to or greater than nominal cell capacity, and, consequently, in this sense it may constitute a useful contribution to network management methods. The simulation model was built following a methodology to assure increasing conceptual model validation.
