An Energy Efficient TDMA based MAC Protocol for Wireless Body Area Networks

Abstract

Wireless Sensor Networks (WSN) and Wireless Body Area Network (WBAN) combined together with modern health care systems are the future of healthcare practices. WBAN witness an upward interest in healthcare sector and is more advanced than any existing telemedicine system. WBAN is an upgraded version of WSN in which number of sensors used are very less in number as compared to WSN and used for monitoring health care. Energy utilization and network lifetime are the main two major challenges in WBAN as recharging and replace batteries of sensors attached to a human body may lead to one’s uneasiness. In recent years, research has been focused on channel modelling, energy consumption, design of efficient medium access control (MAC) protocols for body area networks. For handling emergency data of networks, in this paper, we deployed in numerous practical WBAN scenarios using MAC protocol and tested in more generic Time Division Multiple access (TDMA) approach for avoid packet collision which leads to higher packet loss rate. It is tested in more generic topologies, contrasting the model’s efficiency to the highly esteemed and most remarkable methodologies in the literature. Simulation results show improved performance of the proposed protocols in comparison to the selected existing ones in terms of the chosen performance metrics.
