Performancle Analysis of Microcellisation with Channel Reservation, for Supporting Two Mobility Classes in Cellular Wireless Networks

We study a two layer cellular wireless network supporting two mobility classes, and with channel reservation for different types of calls in the two layers. Fast calls are always assigned a channel in the macrolayer; a slow call first attempts to get a channel in the microlayer and, if blocked there, overflows to the macrolayer. Channels are reserved for fast calls in the macrolayer, and for handoff calls in both the layers. Various approximate analyses of an isolated cell are used to iteratively compute the blocking and dropping probabilities, and are compared with simulations. Finally, using a combination of approximate analysis and simulation, we propose a method to design a cellular network with specified grade of service (GoS). Such an approach results in a huge saving of computation time
