abstract: Delay/Disruption-Tolerant Networking (DTN) is addressed. It is a communication paradigm that enables
the communication over Intermittently-Connected Networks (ICNs), which are characterized by unpredictable
or scheduled contacts among nodes, high latency, and high bit error rates. DTN exploits storeand-forward
techniques in order to cope with intermittent link issues. A model is proposed, to compute the
average packet delivery delay in ICNs. We assume that the inter-meeting time as well as the contact time
between any two nodes is an exponentially-distributed random-variable. As a consequence, the behavior of
the communication between each pair of nodes can be modeled by a two-state Continuous-Time Markov
Chain (CTMC). It is assumed that the packet generation process at the source node follows a Poisson process,
so in the analysis one can exploit the Poisson Arrivals See Time Averages (PASTA) property. Both
the IP-like paradigm used by traditional TCP/IP protocols and DTN are considered. Numerical results and
simulations are presented.
