LOCATION-BASED RANKING AND SWITCHING OF WIRELESS CHANNELS IN A BODY AREA NETWORK OF MEDICAL DEVICES

摘要

Operating techniques and methodologies for a body area network of medical devices are provided. One technique relates to an intelligent channel hopping scheme that detects loss of wireless synchronization on an initial wireless channel, thereafter obtains a measure of quality for the initial wireless channel, and then selects a new wireless channel when the obtained measure of quality fails to satisfy a threshold criteria. Another operating technique dynamically adapts an ordered list of available wireless channels in accordance with a quality measure of the available wireless channels. Thus, when quality degradation associated with a first wireless channel is detected, the ordered list can be updated to indicate a lower preference for the first wireless channel and to indicate a higher preference for a second wireless channel that does not suffer from quality degradation. Another channel hopping or switching technique selects wireless channels in a manner that is influenced by the current geographic position of the medical device.
