Special Issue Information

Dear Colleagues,

Information systems have evolved from centralized, through distributed, to Internet of Things (IoT) architectures. While different in type and scale, ranging from simple home monitoring to complex Industry 4.0 installations, and constructed using different tools and technologies, all require an efficient communication platform to fulfill their purpose.

When dedicated links are not available, in particular, when the cost and flexibility considerations dictate using wireless media, the streams generated by the system components interfere with each other and with unrelated traffic, threatening the realization of application-level functionality. Meanwhile, classical congestion control solutions, involving drops or delay changes as network state indicators, fall short of expectations in the noisy, wireless environment in which temporal conditions undergo significant variations. Therefore, in IoT communication, other measures and congestion control mechanisms should be provided to answer the ever more stringent quality objectives.

This Special Issue targets the current challenges of shaping data transfer in the uncertain, dynamic networking environment of IoT systems. New traffic models, protocols, and control algorithms are needed to handle the diversity of application requirements, while at the same time obeying the resource, energy, and robustness constraints of physical devices.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Delay-tolerant networks (DTNs) are networks where there is no immediate connection between the source and the destination. Instead, nodes in these networks use a store–carry–forward method to route traffic. However, approaches that rely on flooding the network with unlimited copies of messages may not be effective if network resources are limited. On the other hand, quota-based approaches are more resource-efficient but can have low delivery rates and high delivery delays. This paper introduces the Enhanced Message Replication Technique (EMRT), which dynamically adjusts the number of message replicas based on a node’s ability to quickly disseminate the message. This decision is based on factors such as current connections, encounter history, buffer size history, time-to-live values, and energy. The EMRT is applied to three different quota-based protocols: Spray and Wait, Encounter-Based Routing (EBR), and the Destination-Based Routing Protocol (DBRP). The simulation results show that applying the EMRT to these protocols improves the delivery ratio, overhead ratio, and latency average. For example, when combined with Spray and Wait, EBR, and DBRP, the delivery probability is improved by 13%, 8%, and 10%, respectively, while the latency average is reduced by 51%, 14%, and 13%, respectively.
