Smart and interconnected IoT devices offer numerous methods for optimizing workflows and productivity, increasing user experience, and lowering expenses in a diverse range of industries and surroundings. While the advantages of IoT devices may be seen in factories, hospitals, vehicles, homes, and communities, their inherent vulnerabilities bring new security threats and concerns. These flaws expose networks to cyber-attacks, which may seriously destabilize companies and economies.  Impact of IoT Device Security Vulnerabilities  IoT devices are susceptible mostly due to a lack of built-in security measures to safeguard against attackers. The main cause is the restricted environment and these devices' low computing capabilities. IoT devices are often low-power devices that can only perform a limited set of operations. Consequently, they cannot resist the addition of security controls and processes, and data protection measures.  Vulnerabilities in IoT devices may empower cy...

Wireless communication   is currently one of the most rapidly evolving and dynamic technology domains in the communication world. Wireless communication is a way of delivering data from one point to the other without using wires, cables, or any other physical hardware.  In general, data is transmitted from transmitter to receiver over a limited distance. In wireless communication, the transmitter and receiver can be positioned anywhere between a few meters (like a TV remote control) to a few thousand kilometers (Satellite Communication).  We live in a world of communication, and wireless technology is a vital component of our daily life. Mobile phones, GPS receivers, remote controls, Bluetooth audio, and Wi-Fi use  wireless techniques for communication.  Different types of Wireless Communication Systems  Individuals nowadays require mobile phones for a wide range of activities such as conversation, web browsing, multimedia, and more. Each of these services ...
