Congestion control is an important feature that directly affects network performance. Network congestion may cause loss of data or long delays. Although this problem has been studied extensively in the Internet, the solutions for Internet congestion control do not apply readily to challenged network environments such as Delay Tolerant Networks (DTN) where(More)
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(More)
Controlling congestion is critical to ensure adequate network operation and performance. That is especially the case in networks operating in "challenged"- or "extreme" environments where episodic connectivity is part of the network's normal operation. Our goal is to study congestion control mechanisms that have been proposed for these so-called disruption(More)
Unlike TCP/IP networks, in DTNs end-to-end paths between nodes cannot be guaranteed at all times. This means that DTN nodes may have to store messages for long periods of time before they can forward the messages towards their ultimate destinations. As a result, congestion control in DTNs is critical to achieve adequate performance, yet needs to be(More)
