Résumé:
It is well known that the performance of carrier sense multiple access with collision
avoidance (CSMA/CA) is poor when the number of users increases, due to collisions.
In this paper, we consider a modified version of CSMA/CA based on erasure codes at the
packet level, which significantly reduces the complexity of the decoding and does not require
any change in the underlying physical layer. In order to improve the performance, we
use non-binary maximum distance separable (MDS) codes. We give analytical derivation
of the global goodput and show that there is a trade-off between the code parameters and
the length of the contention window in order to maximize the global goodput for a given
number of users.
