| 摘要 |
The present invention concerns a method for characterizing a communication link in a communication network comprising at least two communication nodes and operating using a network protocol comprising a MAC layer and a network layer, said method comprising the steps of: sending unicast packets from a communication node comprising a driver, to another communication node through a link; collecting, by said node at the level of said driver, information concerning transmission characteristics at the level of both MAC layer and network layer; deriving, from said collected information, the following values: delivery ratio of unicast packets; and average time to transmit a unicast packet; and estimating, in said node, the quality of said link at the level of both MAC layer and network layer, by computing the following quantity: mean  ( P   T   T ) du .
