Available Bandwidth Measurement in 4G Networks
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
Existing available bandwidth estimation tools were mainly designed for fixed IP backbone networks and desktops with assumption of First In First Out(FIFO) Principle. While LTE supports high data rates of 100 Mbps, challenge is to adapt available bandwidth algorithms for quick and non-intrusive measurements on an Android OS based device supporting different MIMO configurations.This Master thesis presents real time, two way available bandwidth measurement tool using Two Way Active Measurement Protocol(TWAMP) for Android OS based devices to measure high speed LTE networks. The tool performance is verified against FTP throughput measurement with effect of variation in constant bit rate UDP cross traffic and load on the server on end-to-end measurements. The results from emulation and tests in a commercial LTE network show that we can achieve available bandwidth estimations on both the uplink and downlink in real time. This opens up wide possibility to include various existing available bandwidth techniques and tools in mobile application to be used over a wireless link. Further, possible suggestions to achieve better available bandwidth estimations with native application development has been proposed.
