Although custodial transmission of multicast bundles would be a desirable capability to have in Delay-Tolerant Networks (DTNs), support for custodial multicast transmission was omitted from the Bundle Protocol Specification because of its complexity. This paper explains the difficulties that arise with respect to supporting custody transfer and retransmission of multicast bundles, and it descri...

Due to the increasing use of wireless communications, infrastructure-less networks such as Delay Tolerant Networks (DTNs) should be highly considered. DTN is most suitable where there is an intermittent connection between communicating nodes such as wireless mobile ad hoc network nodes. In general, a message sending node in DTN copies the message and transmits it to nodes which it encounters. A...

1— Vehicular Delay-Tolerant Network (VDTN) appears as a particular application of the Delay-Tolerant Network (DTN) concept to transit networks. In this paper we analyze the use of a VDTN to provide asynchronous Internet access on a rural remote region scenario. Through simulation we evaluate the impact of a shortest path based movement model on the performance of four DTN routing protocols in r...

Providing effective telecommunication services over interplanetary networks poses a number of open challenges because of severe impairments exhibited in such environment. In this perspective, this work proposes a coding framework, integrated within the Delay Tolerant Network (DTN) architecture, implementing adaptive erasure coding schemes that rely upon partial observation of the transmission c...
