At the ingress edge node of VDTNs, bundle aggregation process assemblies incoming IP Packets (datagrams) from the higher layer into bundles. When bundles reach the destination edge node, they are de-aggregated in order to retrieve the original IP packets, forwarding them to the upper layers.
Data aggregation is the process where raw data are gathered, reformatted, and presented in a summary form. Data aggregation is an essential component of data management, especially nowadays when more and more data providers (e.g., Google, Facebook, National Aeronautics and Space Administration, and National Oceanic and …

Optimal decision-making in a multi-agent system with uncertainty [1,2,3] in the non-stationary environment [4,5,6] is a challenging problem.Reinforcement learning (RL) [7,8] is an effective method to yield the optimal decision of the multi-agent system based on the Markov decision-making process and dynamic programming [9,10,11,12,13,14]. ...
On the basis of the aforementioned architecture, we focus on the resource allocation process in DTN-IIoT NS, model the DT-assisted resource allocation for highly personalized IIoT services, propose the service equilibrium rate, and formulate the optimization problem aiming at maximizing the equilibrium rate weighted net profit of …
Delay/disruption tolerant networking (DTN) is considered one of the most suitable technologies for implementing a space system of systems (SoS) internetworking architecture. Aggregation of multiple DTN bundles within a data transport block, which was proposed to resist space channel asymmetry, has been a controversy for years. In this …

The second option is called medium aggregation where the aggregation only happens in a DTN group level and no aggregation or information hiding is conducted at the intermediate upstream DTN gateway(s). Thus the source knows all the DTN gateways (e.g. L1, L2, N1, and M2) whose groups have members interested in the P2MP session.
This work examines how Saratoga can be adapted to serve as an efficient convergence layer for delay-tolerant networking (DTN), by transferring DTN bundles as well as files, which will allow DTN networks to increase efficiency of communication across briefly-available disrupted links.
On Tuesday, Brent and WTI oil marked the lowest front-month contract settlements since June 27, according to Dow Jones Market Data.January gasoline RBF24 gained 1.9% to $2.0179 a gallon, while ...
An experimental investigation of whether or not the aggregation of multiple DTN bundles within a single data transport block has performance advantage is presented and a model is developed for the minimum number of data bundles that should be aggregated within a Licklider transmission protocol block. Delay/disruption tolerant …
Creating the aggregation package. We can now use the cookiecutter template to create a package for the aggregation process, called apd.aggregation. Change to the parent directory of the apd.code directory, but there's no need to create a directory for the aggregation process as our cookiecutter template does this.
DECATUR, Ill. (DTN) -- Taking soybean production to the next level requires a different thought process. DTN asked Greg McClure and his son, Cameron, who farm near St. Francisville, Illinois, to ...

Over the weekend, multiple livestock producers emailed DTN staff asking questions about claims made by freshman Rep. Kat Cammack, R-Fla., a member of the House Agriculture and listed at age 33 as ...
A bundler ensures that after bundling, the names of the generated files contain the correct fingerprint. As it is very difficult to combine multiple source files of certain asset classes like images and text, finger is an important performance technology. Paired with code splitting, it is a powerful tool.
In this paper, we present an experimental investigation, using a PC-based testbed, of whether aggregation of multiple DTN bundles within a single Licklider transmission protocol (LTP) block has performance advantage over the default approach of "one bundle per block" for channelrate asymmetric cislunar communications.
Delay or stop (DTN) tolerance space network is considered to be a technology that can trade with a limited or restricted field communication area. In the space DTN network architecture, routing is very important. This article is based on the best-in-class multiattribute decision-making DTN network routing optimization algorithm. The goal is to …

Optimising DTN Configurations. There are many factors that affect the performance of data transfers. To achieve a high level of performance, ensuring the DTN elements of a Science DMZ deployment are well configured and well-tuned is of key importance.
