Center node: "cloud and cache aided wireless networks fundamental latency trade offs"
  Abstract: A cloud and cache-aided wireless network architecture is studied in which edge-nodes (ENs), such as base stations, are connected to a cloud processor via dedicated fronthaul links, while also being endowed with caches. Cloud processing enables the centralized implementation of cooperative transmission strategies at the ENs, albeit at the cost of an increased latency due to fronthaul transfer. In contrast, the proactive caching of popular content at the ENs allows for the low-latency delivery of the cached files, but with generally limited opportunities for cooperative transmission among the ENs. The interplay between cloud processing and edge caching is addressed from an information-theoretic viewpoint by investigating the fundamental limits of a high Signal-to-Noise-Ratio (SNR) metric, termed normalized delivery time (NDT), which captures the worst-case latency for delivering any requested content to the users. The NDT is defined under the assumption of either serial or pipelined fronthaul-edge transmissions, and is studied as a function of fronthaul and cache capacity constraints. Transmission policies that encompass the caching phase as well as the transmission phase across both fronthaul and wireless, or edge, segments are proposed, with the aim of minimizing the NDT for given fronthaul and cache capacity constraints. Informationtheoretic lower bounds on the NDT are also derived. Achievability arguments and lower bounds are leveraged to characterize the minimal NDT in a number of important special cases, including systems with no caching capability, as well as to prove that the proposed schemes achieve optimality within a constant multiplicative factor of 2 for all values of the problem parameters.
