A representative characterisation of inter-contact times between
nodes is essential for the performance evaluation of
mobile networks. The most common characterization of
inter-contact times is based on the study of the aggregate
distribution of contacts between individual pairs of nodes.
The problem with this aggregate distribution is that it is not
always representative of the individual pair distributions, especially
in the short term and when the number of nodes in
the network is high. Thus, deriving results from this characterisation,
can lead to inaccurate performance evaluations
results.
In this paper, we propose and evaluate two new methods
for characterising the inter-contact times distribution in mobile
networks. We prove that these characterizations have
a higher representativeness, thereby improving the accuracy
of the derived performance results. For evaluating the precision
of the different characterizations we use the epidemic
routing protocol, which has an analytical performance expression
that is based on a contact rate λ. We derive from
each of the characterizations the corresponding λ values.
Then, we compare the results obtained using the analytical
expression with simulation results using both synthetic
and real contact traces. It is shown that the new characterization
methods are very accurate, even for reduced contact
traces and high number of nodes.
