QoE Model Based Optimization for Resource Allocation in Wireless Network

• 1、Beijing University of Posts and Telecommunications

Abstract：With the development of mobile devices, one of the hot research topics for wireless communication technologies has begun to transfer from Quality of Service (QoS) to better Quality of Experiences (QoE). Services such as high-definition (HD) online video, high quality online music and IP-based TV need a lot of wireless resources. Users require more efficient resource allocation method to satisfy their QoE expectations. However, the existing resource allocation strategies cannot give integrative consideration to user's experience. Consequently, a breakthrough optimization is necessary. This paper proposes a QoE model in wireless network. Network conditions, equipment properties and environmental interferences are collected. Based on the collection, user's resource requirement is analyzed. Finally, we optimize the resource allocation strategy based on the analysis above. The system level simulation results indicate that this resource allocation method is applicable for the effectiveness of network resource utilization as well as the improvement of users' average satisfaction
