Wireless networks refer to a telecommunications network that allows devices to communicate with each other without the use of physical wired connections. This technology enables users to access the internet, send and receive data, and make calls using radio waves instead of cables. Research in wireless networks involves developing new technologies, protocols, and algorithms to improve the performance, security, and reliability of wireless communication. This includes topics such as the design of efficient routing algorithms, optimization of network resources, development of new wireless standards, and enhancement of wireless security protocols. Overall, research in wireless networks aims to create faster, more reliable, and more secure wireless communication systems to meet the growing demands of modern networks and devices.
