ContextShift: a Model for EfficientDelivery of Content in MobileNetworks
2010 (English)In: Wireless Communications & Networking Conference, 2010Conference paper (Refereed)
A context aware model for delivery of content inmobile networks is introduced and studied through simulation.The model is based on predictive knowledge of mobile userand mobile group behavior. The predictive behavior is relatedto consumption of mobile content on smart mobile terminals.The model proposes to change the time and the location ofthe delivery of predicted content consumption to optimize thewireless network utilization and to improve the user experience.Different content delivery strategies, considering pre-fetchingat the user terminals, caching at the base stations and multi-cast wireless transmissions are proposed and investigated. Thesimulation results show substantial gains in the content deliveryefficiency of cellular networks and improved user perceivedquality for a number of realistic network operation regimes.
