Priority Based Energy Efficient MAC Protocol by Varying Data Rate for Wireless Body Area Network.

Wireless Body Area Network (WBAN) is a cutting-edge technology that is being used in healthcare applications to monitor critical events in the human body. WBAN is a collection of in-body and on-body sensors that monitor human physical parameters such as temperature, blood pressure, pulse rate, oxygen level, body motion, and so on. They sense the data and communicate it to the Body Area Network (BAN) Coordinator. Themain challenge for the WBANis energy consumption. These issues can be addressed by implementing an effectiveMediumAccessControl (MAC) protocol that reduces energy consumption and increases network lifetime. The purpose of the study is to minimize the energy consumption and minimize the delay using IEEE 802.15.4 standard. In our proposed work, if any critical events have occurred the proposed work is to classify and prioritize the data. We gave priority to the highly critical data to get the Guarantee Tine Slots (GTS) in IEEE 802.15.4 standard superframe to achieve greater energy efficiency. The proposed MAC provides higher data rates for critical data based on the history and current condition and also provides the best reliable service to high critical data and critical data by predicting node similarity. As an outcome, we proposed aMAC protocol for VariableData Rates (MVDR). When compared to existingMACprotocols, theMVDR performed verywellwith lowenergy intake, less interruption, and an enhanced packet-sharing ratio. [ABSTRACT FROM AUTHOR]
