A Medical Body Area Network (MBAN) (10) includes a hub device (18) with a wireless communication transceiver (34). One or more sensor devices (14) each include a physiological sensor (24) for acquiring physiological data and a wireless communication transceiver (22) configured to connect with the wireless communication transceiver (34) of the hub device (18) to wirelessly transmit acquired physiological data to the hub device (18). One or more aggregator devices (16) each include a wireless communication transceiver (30) for receiving physiological data acquired by the one or more sensor devices (14). The hub device (18) is configured to respond to not wirelessly receiving a missing data portion of physiological data acquired by a sensor device (14) by requesting and receiving the missing data portion from an aggregator device (16).
