Wireless Body Area Network (WBAN) has become a reality where patient health conditions can be monitored remotely. Lightweight small sensor devices gather the health parameters and transmit the data to a remotely located medical facility. These kinds of resource-constrained networks are prone to several routing attacks, which can disrupt the whole network. Cryptographic approaches are The Wireless Personal Area Network (WPAN) is a network that covers the smallest geographical area and caters to the needs of a single user. A PAN includes one or a few more computers, peripheral devices, telephones, video game consoles and other entertainment devices. However, if multiple users are connecting their devices within the same A wireless personal area network (WPAN) is a PAN carried over a low-powered, short-distance wireless network technology such as IrDA, Wireless USB, Bluetooth or Zigbee. The reach of a WPAN varies from a few centimeters to a few meters. WPAN : Wireless Personal Area Network in short known as WPAN. Actually WPAN is PAN (Personal Area Network) where the interconnected devices are centered around a person's workspace and connected through wireless medium. A Wireless Personal Area Network (WPAN) refers to a short-range wireless communication technology used for interconnecting devices such as smartphones, wearable devices, and other electronics without cables or wires. WPANs have numerous applications including home automation systems and the Internet of Things (IoT) technologies. 2. Permits the interconnection of IT devices in the vicinity of a single user to be managed. It consists primarily of network-enabled personal devices within a restricted area. WPAN is the term used to describe a wireless connection to the internet. PAN consists of laptops, tablets, and mobile devices. .
