Cross layer content delivery optimization for holistic network design in disaster preparedness and recovery scenarios

摘要

We present a framework for optimizing content delivery in disaster recovery scenarios using a holistic network design. Our methodology proposes two main novelties compared to state-of-the-art. First, we propose to model the communication network following a holistic approach. This framework guarantees generality and robustness of the overall design since any network can be considered as part of the different instantiations of a disaster scenario. Second, we characterize the particular network instantiations via their min-cut (well-known parameter from graph theory), which we use to formulate a cross-layer optimization problem aiming at procuring Quality of Service (QoS) and Quality of Perception (QoP) of content delivery. Our results show the benefits of our proposal compared to non-cross layer strategies not designed holistically, by maintaining a level of QoS and QoP in spite of changing network conditions.
