GC-DTN 2022 : Special Issue : Green Communications under Delay Tolerant Networking

Dear Colleagues,

In the near future, we expect the appearance of new services with very distinct features, ranging from mMTC to URLLC. In order to fulfill the requirements of such services, we foresee an unprecedented network densification in the forthcoming years, which will require, among other aspects, the convergence of a large number of wireless technologies. On top of that, the adoption of new networking techniques and solutions, particularly those based on virtualization, fosters network adaptability, overcoming traditional Self Organized Network (SON) techniques.

Although energy efficiency has played a key role in the management of communications networks, the research community, and society in general, has remarkably increased the attention paid to this parameter. Among the different services that will emerge in the next years, those that are less demanding (in terms of time requirements), such as Delay-Tolerant Networks (DTNs), will allow for more flexibility and thus energy savings.

This Special Issue aims to gather original studies related to energy efficiency under DTNs, innovative proposals for future networks using novel techniques, solutions for IoT/M2M services, and exploitation of virtualization techniques to develop adaptable networks. Relevant topics of interest include, but are not limited to:

Application of Low-Power Wide-Area Network (LPWAN) technologies (LoRa, SigFox, etc.) for delay-tolerant IoT/M2M services;
Energy-aware routing techniques for IoT/M2M scenarios;
IoT/M2M transport-level (MQTT, SOAP, etc.) solutions for energy reduction in delay-tolerant services;
Source and network coding for energy-aware DTNs;
Network Function Virtualization (NFV) and Software Defined Network (SDN) techniques applied to energy minimization;
Energy-aware solutions for C-RAN/vRAN architectures;
Energy consumption reduction in Fog/Cloud-based service provisioning
