Performance, Reliability and Scalability of IoT Systems

Dear Colleagues,

The development of IoT systems poses serious problems in terms of quality of service (QoS) assurance. The availability of massive amounts of data collected by heterogenous sensors, the need for their analysis, and the demand of quick reactions at the occurrence of certain events make the design of such systems quite challenging. In many cases, these requirements conflict with the need for low-cost and low-power consumption of most of the devices. Furthermore, the scalability of the devised solutions must be considered, since workloads may depend on many unpredictable factors that can generate peaks of resource demands. This can undermine the availability of the services due to saturation of the system’s service capacity.

For these reasons, performance and reliability modeling, analysis, and simulation as well as on-field measurements play crucial roles in the design of IoT systems.

This Special Issue welcomes either methodological, applicative or experimental contributions with respect (but not limited) to the following areas of interest:

• Performance and scalability of the communication protocols;
• Reliability of communication systems and of systems in general;
• Data offloading policies;
• Quantitative analysis of interactions with fog computing and cloud architectures;
• Workload characterization in IoT;
• Design of new energy-aware communication protocols for sensor nodes;
• Development of models for the early evaluation of IoT system performance and reliability properties.

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. Sensors is an international peer-reviewed open access semimonthly 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 2600 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.
