Abstract

In this paper, we investigate the load balancing problem by jointly considering sectorization and hybrid F/CDMA scheme in the scenario of non-uniform traffic distributions The problem is formulated as a mathematical optimization model, and is solved by Lagrangean relaxation approach The model objective is to minimize weighted blocking probability in terms of distribution diversity To evaluate the model, performance analysis of adaptive load balancing is conducted by proposed bandwidth segmentation scheme; it is denoted adaptive scheme (AS) Non-adaptive (NA) approach by common power control scheme is compared Combining sectorization and bandwidth segmentation scheme provides novel adaptive load balancing Performance improvement that proposed adaptive scheme outperforms common power control scheme is about 50%.
