Abstract :
The concept of a multilayer hierarchical cellular structure is explored for handling voice and data teletraffic in a wide area mobile radio network. At the microcells in the first layer, special attention is paid to handoff calls through channel reservation. The second layer is a macrocell that overlaid a number of microcells. More attention is devoted to handoff voice call and data session through reservation and queuing at the macrocell layer. The mathematical analysis of the proposed structure is presented and its performance is evaluated in terms of the blocking probability and the handoff failure probability of both voice and data traffic at the end of each layer.
