Distributed delay-aware rate control algorithm for the reverse-link of CDMA systems
We propose a new distributed rate control algorithm for the reverse link of CDMA systems. Specifically, when the statistics of packet arrivals are known locally to each access terminal (AT), this new algorithm aims to provide a means to control the relative delay that each AT experiences. For this algorithm, assuming that the arrival process is Poisson and stationary, it is shown through simulations that all ATs experience an equal amount of average delay when the system is underloaded, and the same packet drop probability when the system is overloaded. Furthermore, we propose a modification to the algorithm that gives priority to some desired ATs, and reduces their relative average delay. Finally, simulation results indicate that the algorithm achieves similar short-term average delay even when the packet arrival process is not stationary. © 2006 IEEE.
