Wireless Sensor Networks (WSNs) are used in a variety of applications today and will be used in even more applications in the future. However, WSNs tend to be less reliable than the wired networks we commonly work with mainly due to cheap hardware, low-power radios (with limited range) and limited energy supplies. An increasing number of applications especially in the context of industrial scen...

This document describes an architecture for delay-tolerant and disruption-tolerant networks, and is an evolution of the architecture originally designed for the Interplanetary Internet, a communication system envisioned to provide Internet-like services across interplanetary distances in support of deep space exploration. This document describes an architecture that addresses a variety of probl...

Existing forwarding strategies for delay tolerant networks aim at network throughput maximization. They provide forwarding opportunities to more reachable destinations. This results in the long endto-end delay and low throughput of less reachable destinations. In this paper, we propose two forwarding strategies to improve the throughput of less reachable nodes with little throughput degradation...

Routing in disconnected delay-tolerant mobile ad hoc networks (MANETs) continues to be a challenging issue. Several works have been done to address the routing issues using the social behaviors of each node. Mobile Social Networks (MSNs) are increasingly popular type of Delay Tolerant Networks (DTNs). The routing performance improves when knowledge regarding the expected topology and the social...

Delay Tolerant Networks (DTN) which have sufficient state information include trajectory and contact information, to protect routing efficiency. However, state information is dynamic and hard to obtain without a global and/or long-term collection process. To deal with these problems, the internal social features of each node are introduced in the network to perform the routing process. This typ...

A delay/disruption tolerant network (DTN) architecture was proposed to effectively support communication in challenging scenarios characterized by intermittent connectivity and long latency. The custody transfer (CT) mechanism is used to improve the reliability of DTN. We proposed a mathematical model of the DTN data link. Based on this model, we simplified a link containing both nodes with and...
