Abstract
This paper describes the design, implementation and use of a wireless data network test-bed to support a facilitator-led experiment measuring the quality of service (QoS) of selected mobile applications. The test-bed comprised a wireless LAN, wireless-capable Personal Digital Assistants acting as "3G-like" terminals, with a network performance emulator at the IP-layer providing controlled, reproducible mappings between application-specific QoS and relevant network parameters. The mapping process uses a QoS framework with a top-down view of quality, and a layered OSI-based hierarchy with linkage between performance attributes of adjacent layers. Finally, we illustrate a technique to estimate whether a wireless access technology could satisfy customers' QoS expectations.
