Wireless service providers need to be able to continuously monitor the network Quality-of-Service (QoS) and the Quality-of-Experience (QoE) received by its users. This is so that the providers can collect the necessary feedback to optimize their networks, in order to achieve customer satisfaction while operating cost-effectively. With the increasing computational capabilities of mobile devices, it is now possible to instrument these programmable devices with automated network QoS and QoE measurement software, to conduct large-scale, extensive field measurements in a distributed, scalable and yet cost-effective manner. To realize this endeavor, we propose to design and develop a configurable, scalable and extensible measurement platform on mobile devices that will allow us to monitor network-level QoS performance metrics, do real-time mining of the collected data and perform real-time estimation of the user-perceived QoE of multimedia streams. Using this distributed platform, we will conduct extensive field measurements on commercial wide-area wireless networks to evaluate the joint effects of wireless network transmission artifacts, heterogeneous mobile devices, multimedia content and codec parameters, on the perceived QoE of multimedia streams. The findings of these measurements will provide critical data and insights for the providers to re-engineer and optimize their wireless networks for different types of emerging multimedia services.
