摘要：Providing real-time and the best healthcare facilities for the Pilgrims at overcrowded ritual sites is an emerging research issue, and a considerable challenge thus requires promising healthcare technology. Wireless Body Sensor Networks (WBSNs) is a modern healthcare technology has been proposed to facilitate the healthcare problems that consist of tiny sensors and a coordinator. The research aims to efficiently deal with pilgrims' heterogeneous physiological data through WBSNs at overcrowded ritual site. Therefore, a severity-priority index table, along with the data threshold value of various normal medical and emergency traffic, is created. By using classified normal and emergency medical data, we define multiple levels of data priority to be used by the coordinator of WBSN. In WBSN medium to minimize the overall delay, a preemptive queue-based modified Medium Access Control (MAC) superframe is proposed. In the proposed IEEE802.15.6 based MAC superframe for transmitting normal medical data, a Managed Access Period (MAP) and for the emergency medical data, and Exclusive Access Period (EAP) are preferred. From the numerical analysis, we have seen that the heterogeneous medical data with the highest priority are able to access the communication channel faster than that of low priority. Hence decreases the overall delay at the system. Thus our proposed analytical model can effectively be handling heterogeneous medical data even when more than one emergency traffic gathers at the coordinator from different sensors for faster transmission to the healthcare centers. To validate the analytical findings a broad experimental work will be carried out in our future research.
