A simulation study for allocation of base stations in mobile communication networks

In actual mobile communication networks, the users' locations, the number of mobile communication users, and their behavior change depending on the time zone. This dependency affects the cell traffic; thus, the allocation of Base Stations (BSs) in the service area is an important problem to be investigated. In this paper we propose a new model for allocation of BSs in mobile communication networks, taking account of user distribution, user movement, channel occupancy, and handover. On the basis of this model, we developed a simulation system and carried out many simulations to evaluate the system performance. For simulations, we consider the actual location of road network and the population distribution in Yamagata City, Japan. We carried out many simulations for various scenarios and parameters. The performance evaluation shows that our simulation system makes a good BS allocation.
