Optimization of Dynamic Channel Allocation Scheme for Cellular Networks Using Genetic Algorithim

The spectrum used for wireless transmissions today is becoming overcrowded, due to the increase in the number of users and applications and the demand for the available frequency bands by the various service providers. The major factor that prevents reuse of these bands is the interference caused by neighboring cells. An efficient method to reduce interference needs to be devised. This paper presents work based on the optimization of dynamic channel allocation using genetic algorithm (GA). This attempts to allocate the channel to users such that overall congestion in the network is minimized by reusing already allocated frequencies. The working of Genetic Algorithm which is used in the optimization procedure is also explained. The optimized channel is then compared with a non-optimized channel to check the efficiency of the genetic algorithm.
