Delay-tolerant networks (DTNs) have the potential to interconnect devices in regions that current networking technology cannot reach. Delay Tolerant Networks are utilized in various operational environments, including those subject to disruption and disconnection and those with high-delay, such as Vehicular ad-hoc Networks (VANET). Vehicular networks can be seen as an example of hybrid delay to...

This paper proposes a Software-Defined Delay Tolerant Networking (SDDTN) architecture as solution to managing large (DTN) networks in scalable manner. work is motivated by the planned deployments of DTN on Moon and beyond deep space. Current space communication involves relatively few nodes heavily deterministic scheduled, which will not be true future. It unclear how these networks, consisting...

Routing in delay tolerant networks (DTN) is a challenging problem because at any given time instance, the probability that there is an end-to-end path from a source to a destination. Opportunistic delay tolerant networks are organized by the sporadic connectivity between their nodes and the lack of stable paths from sender to receiver. Future connections are mostly unknown in these networks sen...

Vehicular Delay-Tolerant Networks (VDTNs) are composed of mobile nodes that communicate wirelessly with each other to forward data despite connectivity issues. This paper focuses on the problem of some nodes trying to impair the communication of a VDTN. In the paper we study the case of nodes that delay the forwarding of messages that is a particularly difficult to detect form of misbehavior. W...
