Query: NV-Fogstore : Device-aware hybrid caching in fog computing environments   Edge caching via the placement of distributed storages throughout the network
is a promising solution to reduce latency and network costs of content
delivery. With the advent of the upcoming 5G future, billions of F-RAN
(Fog-Radio Access Network) nodes will created and used for for the purpose of
Edge Caching. Hence, the total amount of memory deployed at the edge is
expected to increase 100 times.
  Currently, used DRAM-based caches in CDN (Content Delivery Networks) are
extremely power-hungry and costly. Our purpose is to reduce the cost of
ownership and recurring costs (of power consumption) in an F-RAN node while
maintaining Quality of Service.
  For our purpose, we propose NV-FogStore, a scalable hybrid key-value storage
architecture for the utilization of Non-Volatile Memories (such as RRAM, MRAM,
Intel Optane) in Edge Cache.
  We further describe in detail a novel, hierarchical, write-damage, size and
frequency aware content caching policy H-GREEDY for our architecture.
  We show that our policy can be tuned as per performance objectives, to lower
the power, energy consumption and total cost over an only DRAM-based system for
only a relatively smaller trade-off in the average access latency.
