Energy Efficient Communication Using Relationships between Biological Signals for Ubiquitous Health Monitoring

초록

Wireless sensor networks with a star network topology are commonly applied for health monitoring systems To determine the condition of a patient, sensor nodes are attached to the body to transmit the data to a coordinator However, this process is inefficient because the coordinator is always communicating with each sensor node resulting. in a data processing workload for the coordinator that becomes much greater than that of the sensor nodes In this paper, a method is proposed to reduce the number of data transmissions from the sensor nodes to the coordinator by establishing a threshold for data from the biological signals to ensure that only relevant in is transmitted This results in a dramatic reduction in power consumption throughout the entire network
