Effect of non-uniform traffic distributions on load balancing in cellular CDMA systems

Abstract

This paper presents a load balancing model to investigate the effect of non-uniform traffic distributions on load balancing in CDMA system. Applying two traffic models on non-uniform traffic distributions, the impact of traffic non-uniformity on system load balancing is compared with uniform distributions. To evaluate the model, we define both load balancing factor (LBF) and load balancing coefficient (LBC). Results indicate that the more offered traffic is easier to achieving load balancing than the less offered traffic.
