Abstract
In a CDMA network, resource allocation is critical in order to provide suitable signal quality for each user and achieve channel efficiency. The third-generation mobile communication systems (ITU/IMT-2000) must be designed to support wideband services at bit rates as high as 2 Mbps, with the same quality as fixed networks. Mobiles transmitted power has to be controlled to provide each user a reasonable connection while limiting the interference seen by other users. Transmitted rate has also to be controlled to avoid congestion. An adaptive protocol is proposed for controlling mobile calls transmitter power and rate cooperatively when previous work has focused on handling them separately. The active component of this scheme is called Genetic Algorithm for Mobiles Equilibrium (GAME). Based on an evolutionary computational model, the base station tries to achieve an adequate equilibrium between its users. Thereof, each mobile can send its traffic with a suitable power to support it over the different path losses and interference. In the mean time, its battery life is being preserved while limiting the interference seen by neighbors. A significant enhancement in signal quality and power level has been noticed through several experiments.
