Call blocking performance for dynamic channel allocation strategies in microcellular mobile communication systems

In the paper several dynamic channel allocation strategies are simulated and compared with the fixed channel allocation for different microcellular configurations. The blocking probability is calculated for the mean square, the nearest neighbour and the first available strategy. The modified Erlang-B formula is derived for temporarily and spatially variable traffic load. Performance degradation due to the non uniform traffic load is analysed and verified by the computer simulations.
