Query: On the Effects of Subpacketization in Content-Centric Mobile Networks   A large-scale content-centric mobile ad hoc network employing
subpacketization is studied in which each mobile node having finite-size cache
moves according to the reshuffling mobility model and requests a content object
from the library independently at random according to the Zipf popularity
distribution. Instead of assuming that one content object is transferred in a
single time slot, we consider a more challenging scenario where the size of
each content object is considerably large and thus only a subpacket of a file
can be delivered during one time slot, which is motivated by a fast mobility
scenario. Under our mobility model, we consider a single-hop-based content
delivery and characterize the fundamental trade-offs between throughput and
delay. The order-optimal throughput-delay trade-off is analyzed by presenting
the following two content reception strategies: the sequential reception for
uncoded caching and the random reception for maximum distance separable
(MDS)-coded caching. We also perform numerical evaluation to validate our
analytical results. In particular, we conduct performance comparisons between
the uncoded caching and the MDS-coded caching strategies by identifying the
regimes in which the performance difference between the two caching strategies
becomes prominent with respect to system parameters such as the Zipf exponent
and the number of subpackets. In addition, we extend our study to the random
walk mobility scenario and show that our main results are essentially the same
as those in the reshuffling mobility model.
