Measuring Impact of QoS on QoE in Mobile Web Services

With the development of mobile web services, it is important to know for a service provider how Quality of Service (QoS) is related with the Quality of Experience (QoE) for the mobile users. Any change in the QoS could be reflected on the QoE. However, good QoS does not always provide good QoE. Thus, a proper combination of QoS and QoE results in a good user experience. Good understanding of QoS and QoE is necessary in order to achieve that. In addition, identifying the proper relationship between network level QoS and user-end QoE is extremely challenging task which requires the highest level of accuracy.
In order to understand the relation between QoS and QoE in a web service, an Apache server was setup with Google Map Web Service. In the server side, QoS parameters- delay, jitter and service unavailability were introduced for an experiment. In the user end, QoE was examined by doing experiment with different mobiles. In this test, 18 different conditions were experienced by the user who marked their QoE. This experiment was designed to collect data from the user to examine the user QoE and network level QoS.
The results show that without server end Apache QoS module the service might be unavailable in high delay and jitter. However, with the Apache QoS module the service is available in high delay and jitter even though it takes longer time to respond. For better QoE, the delay and jitter should be as low as possible. Moreover, better QoE is experienced in better mobile design. Good mobile receiver and resolution make the QoE higher. Lower quality mobile design cannot ensure good service even though the network level QoS is good.
