Apparatus and method for maintaining reliability of wireless network having asymmetric or other low quality wireless links

摘要

A method includes receiving link quality information associated with multiple wireless connections in a wireless network. The method also includes identifying at least one asymmetric communication path in the wireless network using the link quality information. The link quality information could include a statistical value for each of the wireless connections. Identifying the at least one asymmetric communication path could include identifying a first and a second of the statistical values associated with a first and a second of the wireless connections, respectively, and determining whether a difference between the first and second statistical values exceeds a threshold. The method could further include applying a heuristic to indicate that the first and second wireless connections do not form an asymmetric communication path even if the difference between the first and second statistical values exceeds the threshold.

1. A method comprising:
receiving link quality information associated with multiple wireless connections in a wireless network; and identifying at least one asymmetric communication path in the wireless network using the link quality information; wherein the multiple wireless connections include a first unidirectional wireless connection from a first wireless device to a second wireless device and a second unidirectional wireless connection from the second wireless device to the first wireless device; wherein the link quality information includes first and second statistical values associated with the first and second unidirectional wireless connections, respectively; wherein the first and second unidirectional wireless connections between the first and second wireless devices are identified as forming an asymmetric communication path when a difference between the first and second statistical values exceeds a first threshold and at least one of the first and second statistical values does not exceed a second threshold; and wherein the first and second unidirectional wireless connections between the first and second wireless devices are identified as not forming an asymmetric communication path when both the first and second statistical values exceed the second threshold even if the difference between the first and second statistical values exceeds the first threshold.
