Reliable Packet Delivery in Wireless Body Area Networks Using TCDMA Algorithm for e-Health Monitoring system

摘要

Recent advancements in wireless technologies enabled healthcare sector to deliver a wide range of efficient e-Health services through Wireless Body Area Network (WBAN). A WBAN monitors the physiological signals and send corresponding data through wireless transmission. Reliable transmission of data assumes more importance in the case of WBAN. A decision-making algorithm is mandatory for selecting critical data for reliable packet delivery to reduce the chance of casualty. This paper proposes a new algorithm called Time Criticality based Decision Making Algorithm for reliable and preferential transmission of critical data. To achieve this decision making, a lower and upper threshold limit is set for each body parameter. Any data outside the interval specified by these thresholds are considered abnormal and transmitted by the coordinator. Proposed work shows a better performance in terms of Packet Delivery Ratio, throughput and normal energy utilization than Priority based Allocation of Time Slots and other time division based techniques. These Healthcare services enable to monitor patients not only in hospitals and medical center but also from remote locations without affecting the patient's usual activities.
