Masters Description

The development of a performance analysis tool for broadband wireless

Summary: The objective is to develop and implement a performance analysis tool based upon an advanced statistical technique known as large deviation theory (LDT). In particular, it is intended to employ the recently developed theory of effective bandwidths in order to accurately quantify resource usage. Many problems in admission control and network resource dimensioning can be simplified with the use of an accurate and unifying approach to resource usage.

The study concentrates on the application of this tool to traffic engineering on broadband wireless networks. Traffic engineering is an important requirement for supporting real-time services such as Voice over IP (VoIP) and video streaming with quality of service (QoS) guarantees.

Traditional approaches based upon elaborate traffic models are inadequate in the context of large multi-service networks carrying traffic of different types. The approach here will be to use statistics not as a means to fit traffic measurements to a model but rather as a tool to directly measure a statistical property that is called the rate function or entropy.
