Abstract

In the health-care system, parameters of patients such as Electroencephalogram (EEG), Electrocardiogram (ECG), Electromyogram (EMG), Glucose, Blood pressure, motion, etc. are monitored in real-time that assist doctors to timely detect and treat unexpected risks of patients. Thus, it is critical for collected sensor data seamlessly roaming between various types of wireless transmission networks such as Personal Area Network (PAN), Wireless Fidelity (WiFi), Long Term Evolution (LTE). Moreover, congestion carrier frequency between multiple close-by PANs can cause high packet drop rates and useless energy consumption of sensors. From above reasons, we proposed a protocol for PAN-gateway to integrate many wireless communication standards (typically ZigBee, WiFi, LTE) and an optimal control network algorithm for Quality of Service (QoS). Flows of sensor data are seamlessly transmitted through many wireless interface standards in order to achieved the best average data rate; sensor energy used effectively and fairness/priority between many users.
