Description
Summary:Wearable wireless sensors, or Wireless Body Sensor Network (WBSN), is one of the most recent fields of research in healthcare applications. The sensors are placed on the human body to detect the critical medical parameters and transmit the collected data to a centralized node. Though the devices work at low energy and power constraints, maintenance of such devices is a crucial aspect. In light of this requirement, an efficient medium access control (MAC) protocol should be utilized to extend the life time of the network. In this paper, we propose a new “Priority based Energy Efficient (PrEE) MAC protocol” incorporated with various priorities in predefined devices based on data sensing and normal devices changing to priority when the value is more than the threshold, by modifying IEEE 802.15.4 header bits. The PrEE MAC protocol is designed based on the IEEE 802.15.4 and its Superframe structure. The simulation results show that the energy efficiency and lifetime of the proposed MAC protocol is more as compared to the existing MAC protocol.
