When configuring a delay tolerant network (DTN), there are many aspects that need to be taken into consideration for an effective and efficient network. One aspect is a buffer management strategy. Buffer strategies are used to determine which packets need to be forwarded or dropped. This paper will focus on the variety of buffer management strategies available, providing a comprehensive survey and...
Delay Tolerant Networks (DTNs) differ from the traditional Mobile Ad Hoc networks (MANETs) in that DTNs are not always interconnected. The issue of routing data in a DTN is considered here. Many routing protocols exist for DTNs. Some are based on comparing nodes to each other, whereas others focus on the internal properties of the messages they hold. There are wide ranges of protocols, and they perform...
Current DTN systems are vulnerable to malicious attacks by compromised nodes taking advantage of the DTN protocols that control how nodes join and leave the backbone. Without addressing such security issues, DTN systems could result in performance degrade, the compromise of message confidentiality and integrity, and denial of service. Thus, effective mechanisms to identify and fix this vulnerability...

In a Delay Tolerant Network (DTN), where nodes are constantly moving and the connection of nodes are intermittent, messages are delivered by replicating to neighbor nodes in hopes of delivering to the destination in a timely manner. This causes a DTN network to have many duplicates even long after the message has reached its destination. In this paper, we develop a new routing protocol that helps...
