METHOD OF EVALUATING THE QUALITY OF RADIO LINKS FOR A WIRELESS BODY AREA NETWORK, METHOD OF TRANSMITTING MESSAGES FOR A WIRELESS BODY AREA NETWORK, AND DEVICES FOR IMPLEMENTING THOSE METHODS
First Claim
1. A method for evaluating quality of radio links for a wireless body area network comprising at least first and second wireless devices forming a body area network and configured to communicate with each other, at least one of the two wireless devices being mobile relative to the other, said method comprising exploiting messages received by at least one of the wireless devices to measure instantaneous quality of a corresponding radio link and to estimate times during and between which a radio link is reliable, calculating an estimated times reliability indicator, and classifying the radio links as a function of said reliability indicator into at least first and second categories, one of which is a category relating to intermittently reliable radio links taking into account the mobility of the wireless devices of the body area network.

Abstract
A method for evaluating quality of radio links for a wireless body area network includes first and second wireless devices forming a body area network and configured to communicate with each other. One of the two wireless devices is mobile relative to the other, The method includes exploiting messages received by one of the wireless devices to measure instantaneous quality of a corresponding radio link and to estimate times during and between which a radio link is reliable, calculating an estimated times reliability indicator, and classifying the radio links as a function of the reliability indicator into at least first and second categories. One of these categories is a category relating to intermittently reliable radio links taking into account the mobility of the wireless devices of the body area network.

21. An apparatus for transmitting messages across a wireless body area network, said apparatus comprising means for evaluating a quality of radio links in the wireless body area network for communication between wireless devices, and means for routing messages via an intermittently reliable radio link during a period during which the intermittently reliable radio link is considered reliable.
