Effect of Data Rate on Performance of the Wireless Body Area Network

Remote health monitoring utilizing biomedical sensors has seen considerable interest in the late past has been characterized by the advent of a sensor network study field known as the Wireless Body Network (WBAN) Networks. The major challenge of WBAN is that power of sensor nodes is limited due to battery size. The network throughput is influenced by the power usage of the sensor nodes. In past studies many MAC protocols have been investigated. In this paper, Castalia simulator evaluates the impact of different body sensor data levels during no pathloss variations with pathloss variations and multiple access schemes such as the IEEE 802.15.4 TDMA and CSMA (MAC ZigBee protocol).The work performance evaluation shows that if the energy usage, throughput and data collision differences in the TDMA scheme are not apparent. When the time transition results about many drastic drops, the communication between sender nodes and the main computer or center becomes interrupted.
