Special Issue Information

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

Data Exchange in Cluster Structure for Longevity of IoT

In the Internet of Things (IoT), the scope of wireless sensor nodes is extended to things deployed in a pervasive world. For various IoT service applications, things can gather and share their information with each other through self-decision-making. Therefore, we cannot apply the existing information aggregation methods of wireless sensor networks to the IoT environment, which aim to transmit the collected data to only a sink node or a central server. Moreover, since the existing methods involve all the sensor nodes in the process of data exchange, they can cause an increase in the network traffic, delay of data transmission, and amount of energy consumed by things. In this paper, we propose a clustering-property-based data exchange method for efficient energy consumption in IoT networks. First, the proposed method assigns properties to each thing according to the characteristics of the obtained data. Second, it constructs a cluster network considering the location of things and their energy consumption. Finally, the things in a cluster communicate with other things in a different cluster based on their properties. In the experiment, the proposed method exhibits a better performance than the existing method. Owing to the energy-saving effect, we demonstrate that the proposed method results in a more reliable network and improves the longevity of IoT networks. Full article

Mars to Earth Data Downloading: A Directory Synchronization Approach

This paper aims to present a possible alternative to direct file transfer in “challenged networks”, by using DTNbox, a recent application for peer-to-peer directory synchronization between DTN nodes. This application uses the Bundle Protocol (BP) to tackle long delays and link intermittency typical of challenged networks. The directory synchronization approach proposed in the paper consists of delegating the transmission of bulk data files to DTNbox, instead of modifying source applications to interface with the API of a specific BP implementation, or making use of custom scripts for file transfers. The validity of the proposed approach is investigated in the paper by considering a Mars to Earth interplanetary environment. Experiments are carried out by means of Virtual Machines running ION, the NASA-JPL implementation of DTN protocols. The results show that the directory synchronization approach is a valid alternative to direct transfer in interplanetary scenarios such as that considered in the paper. Full article
