In recent years, the realization of an information-centric network
(ICN) in environments where communication links between nodes are
intermittent due to several factors such as uncertainty of wireless
communication and dynamic change of network topology.By introducing an
ICN-based communication paradigm (e.g., name-based communication),
even in a network where communication links are intermittently
connected, efficient content delivery compared with the conventional
host-oriented network can be expected. In the literature, there have
been a number of performance studies using specific routing mechanisms
for request and content message transfers. However, it has not been
sufficiently clarified what type of routing scheme should be chosen
for request and content message transfers, respectively. In this
study, we therefore analytically clarify what type of routing scheme
should be chosen for request and response message transfers in terms
of the average content delivery delay under given link
intermittency. Specifically, the average content delivery delay is
derived particularly when end-to-end and traceback routing schemes are
combined among several combinations of request message routing (i.e.,
end-to-end and epidemic) and content message routing (i.e.,
end-to-end, epidemic and traceback). |
