Issues And Challenges In Implementation Of Wireless Body Area Sensing Networks

ABSTRACT A Body Area Network is a wireless network of wearable computing devices. This paper provides survey on implementation issues of WBAN (Wireless Body Area Network) to be deployed in a medical environment. It describes the challenges in WBAN networks at Physical an MAC layers. It also addresses different protocols used for the transmission of signal. We figured out that the positioning of sensors and receivers, antenna type, complexity of receiver circuit, physical signaling techniques are considered to play a significant role in transmission of the signals. In order to improve efficiency of transmitted signal researchers are working in areas like controlling the power transmission, detecting the distance and handovers between the sensor nodes
