A method of evaluating the quality of radio links for a wireless body network, message transmission method for a wireless body network and devices for the implementation of the method.

摘要

The method involves exploiting messages received by wireless devices of a body area network to measure instantaneous quality of corresponding radio links and to estimate times between which the radio links are reliable. An estimated times reliability indicator is calculated. The radio links are classified into categories based on the reliability indicator, where one of the categories is a category related to intermittently reliable radio links by taking into account of mobility of the wireless devices. The wireless devices are formed of nodes (N1) on right wrist, nodes (N2) on right thigh, nodes (N3) on left hip, nodes (N4) on back, nodes (N5) on left shoulder and nodes (N6) at level of right ear. Independent claims are also included for the following: (1) a device for evaluating quality of radio links for a wireless body area network (2) a method for transmitting messages across a wireless body area network (3) a device for transmitting messages across a wireless body area network.
