2021 International Conference on Communication and Network Security (ICoCNS 2021) will be held in Stockholm, Sweden on August 13-15, 2021. The conference is dedicated to driving innovation in Communications and Network Security and providing researchers and industry experts with an excellent forum to present state of the art research results, exchange visions and ideas, obtain updates on latest advancement of wireless communications, networking and network security, and expand social networking.

The past few years have witnessed a tremendous development in wireless communications and networking, particularly with the recent 5th generation (5G) cellular systems widely being deployed across the globe. New technologies, fundamental theories and applications in communications, networking and network security for beyond 5G and 6G are now being widely discussed and studied.      

The conference committee of ICoCNS 2021 would like to invite researchers and industry experts to submit research papers on the emerging topics of wireless communications, networking and network security for beyond 5G and 6G. The authors are encouraged to participate in this premier international conference to present your research innovations, obtain latest development and promote the advances of the academic research in the field of communications and network security.  

ICoCNS 2021 will be held in the beautiful Stockholm, Sweden, in summer, which is the best season in North Europe. The conference will start with a reception on August 13 2021 followed by two full days of technical sessions consisting of keynote speeches and plenary lectures to overall audience, oral presentations and poster presentations by participants as well as a social networking event. The rich program of ICoCNS 2011 will no doubt stimulate interesting discussions and generate new ideas.

We believe that ICoCNS 2021 will provide the best opportunity and forum for all the participants to have fruitful discussions and exchange ideas on communications and network security. Finally, we do wish all of you to have a memorable experience on the conference and seize this opportunity to promote future international collaborations.
