Ambient Backscattering (AB) is an emerging technology that can be used to replace small battery powered devices. It works
by utilizing the existing ambient signals to harvest energy and propagate its own signal. In this paper, the aim is to propose using AB in
Wireless Body Area Networks (WBAN). WBANs mainly consist of sensors that can be attached on or implanted into the human body,
enabling greater mobility of patients and improving Quality of Life. The sensors record patient vitals, that can be transmitted to a central
hub for monitoring. The recorded patient vitals can then be analyzed by doctors remotely. Telemedicine has enabled physician and
patient interaction and consultation without being physically present at the same place. The growth of Wireless Sensor Nodes is limited
by high cost and energy consumption and AB has the potential to overcome these limitations. Elimination of the RF transmitter will
reduce the size and elimination of the battery will increase the life of the sensor devices, improving overall efficiency of the system.

Introduction of Ambient Backscatter technology into the architecture of WBANs would make a huge difference. WBANs improved the mobility of the patients, but the battery life of these sensors was short and soon would need replacement. This becomes a problem with sensors that must be implanted into the body. With Ambient Backscatter technology making the sensor devices battery-less, it extends the usage period and will solve the battery crunch issues that sensor devices currently face. Thus decreasing/eliminating replacement of sensor nodes. Elimination of the RF transmitter makes the sensor devices smaller in size, lighter in weight and less expensive to manufacture. All the required components are easily available, and no special component is needed to achieve this.-
