TDMA BASED DELAY SENSITIVE AND ENERGY EFFICIENT PROTOCOL FOR WBAN

Abstract

The fundamental function of Wireless Body Area Network (WBAN) is to convey information over short distances. Because of their tremendous potential in medical and home applications, WBANs have raised tremendous research interests in recent years. This paper presents an energy-efficient and delay sensitive medium access control (MAC) protocol suitable for communication in a WBAN for remote monitoring of physiological signals such as EEG, ECG etc. In the proposed scheme, sensors are allowed to interrupt the PDA in case of emergency so that immediate action may be taken to avoid any causality, hence provides support to deal with emergency data along with the normal data. For performance analysis viewpoints the proposed scheme is simulated and compared with IEEE 802.15.4 standard. The simulation results shows that the proposed scheme is better in QoS for emergency (higher priority) data and gives better performance in terms of the average transmission time and energy efficiency
