Delay-Tolerant Networking

Dear Colleagues,

Delay and disruption-tolerant networking (DTN) is an active research topic that has attracted significant attention from researchers. A DTN is a network of challenged-networks that support long delays and data loss between and within challenged networks, with the potential for countless applications in various challenged scenarios and environments. These applications include interplanetary networking, military and tactical systems, disaster recovery networks, wildlife tracking/monitoring sensor networks, vehicular communication, communication in remote and rural areas and developing countries, and many more. In the advent of 5G networking combining many different radio access technologies and the proliferation of edge computing, DTN is expected to obtain considerable value, oftentimes serving as a convergence substrate above the network layer, allowing many different heterogeneous radio networks and applications to inter-operate. Furthermore, software-defined networks (SDNs) will enable flexible definitions of intelligence at the edge network, ranging from well optimized models to rather thin radio clients. DTN can again serve as a dynamic convergence substrate for all heterogeneous devices, computational models, and access networks, enabling interoperation in arbitrary scales of inter-device distances, that is, from the very short-range ones to the extremely long, even inter-planetary ones.

This Special Issue aims at bringing together researchers and practitioners to exchange their ideas, experiences, and latest research results on DTNs and their applications.

The topics of this Special Issue include, but are not limited to, the following:

• DTN architectures, protocols, and algorithms
• Security, privacy, and trust in DTNs
• DTN data management and analytics
• DTN prototypes, testbeds, and case studies
• IoT applications over DTN
• Social network analysis and DTN
• Bundle protocols and applications
• Data fusion, scheduling, and DTN
• Store-carry-forward routing
• Simulation and modelling of DTN
• Cross-layer design and DTN

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Future Internet is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
