Abstract
Different wireless technologies are assumed tocooperate in a single heterogeneous environment in futurenetwork deployment schemes. Such environment is characterizedby a multitude of new services based on multimedia services likegaming and real time video streaming. When dealing with video services, traditional QoS solutionsare not sufficient for ensuring video awareness and good user'sperception. Quality of Experience (QoE) management approachhave been introduced to estimate the quality level of multimediaservices. In an heterogeneous environment every user can switchbetween many networks during his communication in a verticalhandover (VHO) process and QoS may decrease as well as thevideo quality. That is why, maintaining the requested QoS andkeeping a satisfying QoE during a VHO process is the main goalfor HWNs. In this paper, we proposes a QoE-fuzzy vertical handoveralgorithm with QoS management and QoE decision. Simulationresults of the proposed system show performances improvementfor throughput and delays.
