An algorithm for capacity allocation in cellular spread spectrum networks with nonuniform traffic loadings

We propose an algorithm that enables each user in a mobile spread spectrum radio network to select a cell site and a transmitter power level for the uplink communication. From the point of view of a user, the algorithm allocates enough bandwidth to satisfy the user’s bit rate requirement. From the point of view of the network, the algorithm allocates capacity to spatial regions. If a region becomes congested then the network automatically adjusts cell boundaries to accommodate this extra traffic. We compare the capacity under this algorithm with that in which users always select the strongest cell site. In the case of a single traffic hotspot, the capacity of the congested region is shown to be almost three times greater under the proposed algorithm.
