QoE: User Profile Analysis for Multimedia Services

International audienceIn multimedia services, user's perceived quality of service is very important as compared to other end-to-end network factors. With the growth of emerging technologies, it becomes necessary for network service providers (both in the wired and wireless domains) to consider all aspects of network elements, not only to offer a better Quality of Service (QoS) but also to achieve higher end-users satisfaction. The analysis of users' profile provides vital information, which can help service providers in managing their resources efficiently, by analyzing users' behavior and expectation. In this paper, we setup a testbed to investigate the various factors that contribute to the Quality of Experience (QoE), in the context of video streaming delivery over wireless and wired networks. The comprehensive study of users profile provides significant insights on all metrics that influence the QoE (network parameters and video characteristics). Wireless and wired networks have different infrastructure aspects (reliability, availability etc.) but the analysis and evaluations of users' profile are equally important for both networks. Our analytical study gives an opportunity for network service providers to obtain high user satisfaction by providing a service level that matches customers' usage patterns and expectations
