GSM automatic frequency planning with the aid of genetic algorithms

Abstract

Due to the high demand of mobile services, and the full loading of the mobile allocated spectrum, a very tight frequency reuse schemes appeared, and high levels of interference occurred and due to the overlap of cells, which in turn made it very difficult to allocate frequencies for the different cells in the cellular system. Here in this seminar genetic algorithm was implemented as a method to get the optimum frequency allocation for such cases. Alphabetical encoding was used since the problem size and the number of cells in the scope is relatively large, an existing GSM network was used as a model to test the work. Different scenarios were applied on the genetic algorithm to tune and the system parameters and get best performing form of it for such problems
