ICCDN 2021, the 5th International Conference on Communication, Device and Networking, is held in the Department of Electronics and Communication Engineering (ECE) of Sikkim Manipal Institute of Technology (SMIT), Sikkim Manipal University (SMU), Sikkim, December 15–16, 2021. The publication of ICCDN is sponsored by LNEE, Springer (SCOPUS Indexed). The aim of the conference is to provide a platform for researchers, engineers, academicians, and industry professionals to present their recent research works and to explore future trends in various areas of engineering. The conference also brings together both novice and experienced scientists and developers to explore newer scopes; collect new ideas; establish new cooperation between research groups; and exchange ideas, information, techniques, and applications in the field of electronics, communication, devices, and networking. The ICCDN-2021 committees rigorously invited submissions of manuscripts from researchers, scientists, engineers, students, and practitioners across the world related to the relevant themes and tracks of the conference. The call for papers of the conference was divided into six tracks as
mentioned: 

Track 1: Electronics Devices and Nano-technology, 

Track 2: Signal Processing, 

Track 3: Microwave and Millimetre Wave Engineering, 

Track 4: AI and its Application, 

Track 5: Energy, Power and Control, 

Track 6: Communication and Networking. 

On behalf of the executive committee and the local organizing committee, we thank the authors and the participants for their original ideas, innovative applications, and practical achievements in the different fields related to the conference. The conference is enriched with six keynote speeches each of 1 hour duration by eminent speakers from academia and industry. As speakers, we have with us Dr. Debdeep Sarkar from Indian Institute of Science (IISc), Bangalore, India; Dr. Tao Guo, PIESAT Information Technology Co, Ltd, China; Mr. Rampersad, EarthDaily Analytics, Vancouver, Canada; Dr. Rudra Sankar Dhar, NIT Mizoram, India; Dr. Vinayakumar Ravi, Prince Mohammad Bin Fahd University, Khobar, Saudi Arabia; and Dr. Angsuman Sarkar, Kalyani Government Engineering College, West Bengal, India.

A total of 126 papers have been received, out of which 58 papers (including 5 invited papers) have been accepted in the conference. Participants, from different parts of the country as well as across different countries, presented their paper through online platform. All these efforts undertaken by the organizing committees lead to
a high-quality technical conference program, which featured high-impact presentations from keynote speakers and from paper presenters. On behalf of the ICCDN organizing committee, we would like to thank Springer for the kind cooperation. We would like to thank the chief patrons, patron, advisory board members, general
