Abstract: This paper proposes two new congestion control schemes for packet
switched wireless networks. Starting from the seminal work of Kelly (Kelly et
al., Dec 1999), we consider the decentralized flow control model for a TCP-like
scheme and extend it to the wireless scenario. Motivated by the presence of channel
errors, we introduce updates in the part of the model representing the number of
connections the user establishes with the network; this assumption has important
physical interpretation. Specifically, we propose two updates: the first is static,
while the second evolves dynamically. The global stability of both schemes has been
proved; also, a stochastic stability study and the rate of convergence of the two
