USING A FUZZY CONTROLLER FOR THE VERTICAL HANDOVER PROCEDURE

. Due to the rapid development of mobile technologies, there is a situation when several different mobile networks operate on one area. In this case, the main problem for ensuring the required quality of service for subscribers is implemention of an optimal algorithm for fast switching between different network, i.e. performing a vertical handover operation. The paper proposes to utilize a fuzzy controller in the intelligent algorithm of multicriterial vertical handover. We propose to use a fuzzy controller having six input and one output linguistic variables. The rule base consisting of sixty-four rules is presented. Simulation of the developed fuzzy controller in Matlab program was performed.
