In this paper we consider link error or physical channel error in wireless networks and propose a new rate-based congestion control scheme for wireless networks with random losses, based on the network utility maximization framework developed for TCP-like congestion control model in wired networks. The scheme is distributed and can be implemented by changing the number of connections opened by one user and requires no modification to either the network infrastructure, or the network protocols. The scheme is globally stable in the absence of round trip delay of each user and all trajectories can converge to the unique equilibrium point. The convergence rate is also studied and stochastic disturbance is analyzed. Furthermore, a sufficient condition for local stability of the scheme at the equilibrium is obtained in the presence of delay based on the general Nyquist criterion.
