Abstract

Abstract-In the paper, the feature of Intermittently Connected Mobile Networks (ICMN), that information can be propagated through the near-distance contact of nodes, is utilized as a supplement to the common Internet subscriber/publisher services. Specifically, the nodes with Internet connectivity can help those without in retrieving the messages once stored and carried by the former. With the modeling of such a system, especially the consideration of the time-critical messages and limited bandwidth, the message delivery ratio and delay under the 1-hop and 2-hop relaying modes are analyzed respectively with the validation through extensive simulations.
