Application-aware DTN Routing
نویسندگان
چکیده
Delay-tolerant networking (DTN) enables nodes to communicate by means of asynchronous messaging even though no end-to-end path may exist at any point in time. Messages may be of arbitrary size and the (email-style) store-carry-and-forward operation keeps copies of messages in possibly many nodes for an extended period of time. Suitably designed application protocols avoid frequent interactions and create self-contained messages instead. We leverage these properties and propose application support for DTN routers. By adding explicit application hints visible to intermediate DTN nodes the latter can selectively aid application performance, by means of application-dependent routing, cooperative caching, distributed storage, or even more complex operations.

Energy-Aware Probabilistic Epidemic Forwarding Method in Heterogeneous Delay Tolerant Networks
Due to the increasing use of wireless communications, infrastructure-less networks such as Delay Tolerant Networks (DTNs) should be highly considered. DTN is most suitable where there is an intermittent connection between communicating nodes such as wireless mobile ad hoc network nodes. In general, a message sending node in DTN copies the message and transmits it to nodes which it encounters. A...
متن کاملSelf-Adaptive Context Aware Routing Protocol for Unicast Communication in Delay and Tolerant Network
At present, most of research works in mobile network focus on the network overhead of the known path which exists between the sender and the receiver. However, the trend of the current practical application demands is becoming increasingly distributed and decentralized. The Delay and Tolerant Network (DTN) just comes out of such background of the conflicts between them. The DTN could effectivel...
متن کاملEnergy-Aware Forwarding Strategies for Delay Tolerant Network Routing Protocols
Delay Tolerant Networking (DTN) is well suited to challenging environments, defined by the lack of reliable end-to-end communication paths to the destination. However, the available energy is not considered in the majority of existing DTN routing protocols when they make forwarding decisions. This limits both delivery probabilities and the network lifetimes in energy-constrained applications. T...
متن کاملA Socially Aware Routing Based on Local Contact Information in Delay-Tolerant Networks
In delay-tolerant networks, network topology changes dynamically and there is no guarantee of continuous connectivity between any two nodes. These features make DTN routing one of important research issues, and the application of social network metrics has led to the design of recent DTN routing schemes. In this paper, we propose an efficient routing scheme by using a node's local contact histo...
متن کاملThe ONE simulator for DTN protocol evaluation
Delay-tolerant Networking (DTN) enables communication in sparse mobile ad-hoc networks and other challenged environments where traditional networking fails and new routing and application protocols are required. Past experience with DTN routing and application protocols has shown that their performance is highly dependent on the underlying mobility and node characteristics. Evaluating DTN proto...
