The loss of a data frame or of its acknowledgement has a negative impact on the collection of real-time critical data. To avoid delays introduced by error detections and frame repetitions, channel coding is used to ensure a frame is received with minimal or no errors. This contribution is dealing with a wireless sensor network designed for deployment in confined and confined areas and complex environments, such as a launcher equipment bay. A star topology and the use of TDMA for exchanges compliant with the 802.15.4 standard as access method, are the major characteristics of this network. The specified technique evaluated here has been designed for frames carrying short samples of measurements produced by a set of sensor nodes. In this context we evaluate the combined use of a Golay coding and a matrix interleaving. The gain brought to the Frame Error Rate is evaluated according to the length of the frames and the aggressiveness of the medium which behavior is expressed from a logical model.
