Congestion management techniques for disruption-tolerant satellite networks

Congestion management in delay tolerant networks

In delay tolerant networks, custody transfer can provide certain degree of reliability as a custodian node cannot discard a message unless its life time expires or the custody is transferred to another node after a commitment. This creates a challenging decision making problem at a node in determining whether to accept a custody transfer: on one hand, it is beneficial to accept a large number o...

Resource Management of Disruption Tolerant Networks

Disruption tolerant networks (DTNs) differ from traditional networks due to their special characteristics such as frequent partitions, intermittent connectivity, and message delivery delay. This paper presents a new idea for the resource management of sparse disruption tolerant networks where the density of nodes is insufficient to support direct endto-end communications. The idea combines an a...

Congestion control in disruption-tolerant networks: A comparative study for interplanetary and terrestrial networking applications

Controlling congestion is critical to ensure adequate network operation and performance. That is especially the case in networks operating in challengedor extreme environments where episodic connectivity is part of the network’s normal operation. Consequently, the “pure” end-to-end congestion control model employed by the Internet is not adequate. Our goal is to study congestion control mechani...

A survey on congestion control for delay and disruption tolerant networks

Delay and disruption tolerant networks (DTNs) may experience frequent and long-lived connectivity disruptions. Unlike traditional networks, such as the TCP/IP-based Internet, DTNs are often subject to high latency caused by very long propagation delays (e.g., interplanetary communication) and/or intermittent connectivity. Another feature that sets DTNs apart from conventional networks is that t...
