Wireless Body Area Networks: Where Does Energy Go?
Wireless Body Area Networks (WBANs) promise to revolutionize health care in the near future. By integrating bio-sensors with a mobile phone it is possible to monitor an individual's health and related behaviors. Monitoring is done by analyzing the sensor data either on a mobile phone or on a remote server by relaying this information over a wireless network continuously and in real time. However, the "Wireless" aspect of WBAN is being limited by the battery life of the mobile phone. A WBAN designer has a range of options to trade-off limited battery with many important metrics.
