QoE oriented cross-layer design of a resource allocation algorithm in beyond 3G systems

摘要: The provision of high speed access to Internet and IP-based services is one the main goals beyond 3G (B3G) wireless systems. These systems will benefit from cross-layer protocol designs that introduce interactions between different layers obtain performance gains. majority research in field B3G aims at improving quality service (QoS) system centric metrics such as spectral efficiency, latency, delay variation (jitter), etc. However, minor attention has been paid satisfaction subjective requirements human users. With goal incorporating perception into design systems, this work carries out an experimental survey sensitivity user response time for Web browsing application. From results, a mapping data rate (provided by link) mean opinion score (MOS) derived. presented results show page size plays important role function. derived function incorporated radio resource allocation algorithm orthogonal frequency division multiple (OFDMA) This incorporation carried maximizing aggregate utility over all users cell. Its compared multicarrier proportional fair (MPF) under heavy load conditions with LTE simulator. have shown proposed methodology can provide interesting enhancement experienced MPF algorithm.
