Dear Colleagues,

Wireless network technology in the future will advance considerably more quickly than it does now. With this accelerated speed, wireless connectivity will be able to support more aspects of our lives and more sophisticated, data-hungry apps. Reliability: As technology advances, wireless networks will also become more dependable. Billions of individuals can now access the Internet and take advantage of the modern digital economy thanks to wireless communications. Similar to how people can use their mobile phones anywhere in the world thanks to established standards. In 21^st Century the wireless communication applications has tremendously changed and contributed to make human life smarter in comparison with the earlier era. Currently new technologies i.e. Internet of Things, Cloud Computing and Sensor technologies has bring a new trends of smarter environments for the human kind i.e. Smart Cities, Smart Offices, Smart Homes, Smart agriculture etc. In every field of like today we can use gadgets/ tinny sensors to monitor various activities online wirelessly which was not possible in early era. In communication challenges of security, trust, infrastructure, architectures and routing protocols still needed to be improved to address these key challenges under wireless communication.

Thus, we are interested in the research articles i.e. Review/Survey studies, Technical studies in the domain of wireless communication related to the key challenges addressed in this issue.

We look forward to receiving your contributions.
