Performance evaluation of multidimensional traffic in micro-macro cellular system

We evaluate performance of hierarchical network (overlay-underlay cellular system) based on convolution method under mixed offered traffic. In most of the cases, different offered traffic of a network follows different probability density functions and they are correlated in sharing channel environment and cannot be analyzed by equivalent random theory (ERT) model. Here, three different types of offered traffic are considered for determining the blocking probability in the higher-tier cells.
