Abstract

We introduce and propose a new architecture tested solely for a prompt sensing and anytime-connected wireless body area network for the transmission of important physiological signals over cellular networks. Our work considers signals related to cardiac diagnostics for transmission and energy based evaluations in such a network. The physiological data from cardiac parameters is sensed and transmitted over a Wireless Body Area Sensor Network (WBAN) to a coordinator and sink station (CSS). The CSS compresses the data received, processes it and sends it through GSM communication over the cellular network to a remote base station. The GSM receiving unit receives the data and directs it to a dedicated remote server for demodulation and decompression. We have discussed the methods used for the compression of data in this scheme and tried to keep the transmission error low. We propose a dedicated channel in upcoming generations of mobile communication technology for the transmission of vital physiological data. We have also tried to evaluate the network lifetime using common battery models. Our methodology would facilitate round-the-clock health monitoring for the subscribers of a cellular communication system by working in partnership with the underlying body sensor networks consuming low power.
