Abstract: In the medical field, the WBBSNs is employed to monitor physiological signs of patients such as Electro Eencephal Ggram (EEG), Electro Cardiogram (ECG), Heartbeat, Blood Pressure (BP), Temperature, etc. In WBBSNs consists of smart battery-operated biosensors are deployed in/on-body of patients. The main constraint on these networks is the energy consumption and network lifetime. To address this, we proposed Reliable Energy Aware Medium Access Control (REA-MAC) protocol for Wireless Body Bio-Sensor Networks (WBBSNs). This protocol employs Time Division Multiple Access (TDMA) approach for channel access with synchronization approach. To avoid idle listening and overhearing all biosensors remain in sleep mode until the time slot assigned by sink node. The proposed protocol performances are compared in terms of energy and reliability and simulation results shows that performance of overall network is improved by 20% as compared with in IEEE 802.15.4 protocol.
