Atulya K. Nagar - Intelligent Sustainable Systems: Selected Papers of WorldS4 2021, Volume 1

The series Lecture Notes in Networks and Systems publishes the latest developments in Networks and Systemsquickly, informally and with high quality. Original research reported in proceedings and post-proceedings represents the core of LNNS.

Volumes published in LNNS embrace all aspects and subfields of, as well as new challenges in, Networks and Systems.

The series contains proceedings and edited volumes in systems and networks, spanning the areas of Cyber-Physical Systems, Autonomous Systems, Sensor Networks, Control Systems, Energy Systems, Automotive Systems, Biological Systems, Vehicular Networking and Connected Vehicles, Aerospace Systems, Automation, Manufacturing, Smart Grids, Nonlinear Systems, Power Systems, Robotics, Social Systems, Economic Systems and other. Of particular value to both the contributors and the readership are the short publication timeframe and the world-wide distribution and exposure which enable both a wide and rapid dissemination of research output.

The series covers the theory, applications, and perspectives on the state of the art and future developments relevant to systems and networks, decision making, control, complex processes and related areas, as embedded in the fields of interdisciplinary and applied sciences, engineering, computer science, physics, economics, social, and life sciences, as well as the paradigms and methodologies behind them.

Indexed by SCOPUS, INSPEC, WTI Frankfurt eG, zbMATH, SCImago.

All books published in the series are submitted for consideration in Web of Science.

The fifth edition of the WorldS4 2021World Conference on Smart Trends in Systems Security and Sustainabilitywas held during 2930 July 2021 digitally on Zoom and organised by Global Knowledge Research Foundation. The associated partners were Springer, InterYIT IFIP, and IEEE UK and Ireland Sections. The conference provided a useful and wide platform both for the display of the latest research and for the exchange of research results and thoughts. The participants of the conference were from almost every part of the world, with the background of either academia or industry, allowing a real multinational multicultural exchange of experiences and ideas.

A great pool of more than 870 papers were received for this conference from across 28 countries among which around 144 papers were accepted with this Springer Series and were presented through a digital platform during the two days. Due to the overwhelming response, we had to drop many papers in the hierarchy of the quality. Totally, 28 technical sessions were organised in parallel in two days along with few keynotes and panel discussions. The conference involved deep discussion and issues which were intended to solve at global levels. New technologies will be proposed, experiences will be shared, and future solutions for enhancement in systems and security will also be discussed. The final papers will be published in two volumes of proceedings by Springer LNNS Series.

Over the years, this conference has been organised and conceptualised with the collective efforts of a large number of individuals. We would like to thank each of the committee members and the reviewers for their excellent work in reviewing the papers. Grateful acknowledgements are extended to the team of Global Knowledge Research Foundation for their valuable efforts and support.

We look forward to welcome you to the sixth edition of this WorldS4 Conference in 2022.
