A context aware model for the delivery of contentin mobile networks is presented and studied through simulation.The proposed model is based on predictive knowledge of mobileuser behavior related to consumption of content on smartterminals. Content prediction is here exploited to change the timeand the location of content delivery, opportunistically utilizing theinstantaneously available excess of resources in the network. Thisis anticipated both to increase network utilization and to enhanceuser perceived service quality. However, since the accuracy of thecontext information, and associated content predictions, mighthave a significant impact on performances, our investigationshave been accounting for different content prediction capabilitiesas well as for various degrees of similarity in users’ contentrequests. The obtained results show that substantial gains bothin terms of wireless network efficiency and improved user serviceperception can be achieved, as compared to classical contentdelivery methods, for a number of realistic scenarios.
