The demand for efficient, scalable and cost-effective information servers for mobile users is rapidly growing. However, none of the existing service approaches integrates all the characteristics needed to perform efficiently in a real-world, time-constrained asymmetric communication environment. Most of the related research focuses on push-based or pull-based broadcast schemes. In this paper we present an adaptive hybrid data dissemination model that takes into account bandwidth restrictions in downlink and uplink channels, dynamic user access patterns and time constrains associated with data. We show that our approach utilizes the limited bandwidth and computational resources adequately in order to minimize the number of deadlines missed. Performance is evaluated by simulation
