Wireless Body Area Networks – A Review

Abstract

A network is basically formed when two or more computers connect with each other in order to perform certain tasks, it could be data transfer, file exchange etc. The connection could be either a wired or a wireless connection. Before the advent of wireless communication and technology, the devices in a network were physically connected with wires, example optical fibre cable/Ethernet etc. Needless to mention, there most certainly are quite a few limitations associated with wired communication especially in manually unreachable areas. Henceforth, this calls the need for wireless communication between devices. In a wireless medium, instead of using a wired physical media, we use air/RF signals as the communication link in the network. In this review paper, we specifically lay emphasis on Wireless Body Area Networks or (WBAN); its architecture, types, applications, drawbacks etc.
