| Abstract | We consider the application of delay tolerant network (DTN) to provide low-cost de- livery of digital contents to a school in a remote village with no connectivity to the global Internet. The school under consideration is assumed to have frequent visitors who commute between the school and a speci c city/town area. Both the school and the city/town area are equipped with WiFi access points, but only the access point in the city/town is connected to the global Internet. We analyze the average throughput associated with one frequent visitor who volunteers to bring data packets from the city/town to the school via his/her mobile device. To do so, we model the movement of the frequent visitor as well as data packet transfers using a continuous-time Markov chain (CTMC). In addition to the throughput expression, the CTMC is used to derive the expression of the mean packet delay as well as the stability condition for no bu er over ow on a mobile device. Simulation experiments are carried out to validate the correctness of our theoretical derivations as well as to validate the approximation of the system as a CTMC for tractable analysis. The analysis can provide basic understanding in designing practical rural area networks to be self-sustainable. |
