Abstract
A system and method for determining the reliability of at least one communication link between nodes in an ad-hoc communication network. The system and method perform the operations of receiving at a first node data sent by a second node over a link from the second node to the first node, determining a bit error rate (BER) at which the first node received the data, and identifying the link from the second node to the first node as being reliable when a value determined based on at least the BER and, more specifically, an aggregate of the BER and BERs of data received by the first node from the second node over a period of time, meets a desired condition. The data sent by the second node can include routing advertisement data indicating at least one node which is a neighboring node of the second node, or can be any suitable regularly expected message. The data also includes an indication as to the reliability of the link from the first node to the second node based on a measure of at least one previous message, for example, the BER or aggregate BER of at least one routing advertisement, that the second node received from the first node.
