Query: Device-to-Device Coded Caching with Distinct Cache Sizes   This paper considers a cache-aided device-to-device (D2D) system where the
users are equipped with cache memories of different size. During low traffic
hours, a server places content in the users' cache memories, knowing that the
files requested by the users during peak traffic hours will have to be
delivered by D2D transmissions only. The worst-case D2D delivery load is
minimized by jointly designing the uncoded cache placement and linear coded D2D
delivery. Next, a novel lower bound on the D2D delivery load with uncoded
placement is proposed and used in explicitly characterizing the minimum D2D
delivery load (MD2DDL) with uncoded placement for several cases of interest. In
particular, having characterized the MD2DDL for equal cache sizes, it is shown
that the same delivery load can be achieved in the network with users of
unequal cache sizes, provided that the smallest cache size is greater than a
certain threshold. The MD2DDL is also characterized in the small cache size
regime, the large cache size regime, and the three-user case. Comparisons of
the server-based delivery load with the D2D delivery load are provided.
Finally, connections and mathematical parallels between cache-aided D2D systems
and coded distributed computing (CDC) systems are discussed.
