Comparative Evaluation of Soft Computing Techniques in Intersystem Handoff Algorithms




Handoff, Intersystem Handoff, Fuzzy system, Neural System, Soft Computing Techniques


This research work is carried out in the field of inter-system handovers. The next generation communication depends upon many types of co-existing mobile communication Systems/Networks normally GSM/ WCDMA Networks, Satellite communication based networks, high altitude stratospheric platform systems (HAPS). An individual have to move from one area covered by one type system to another area covered by different kind of Technology/Network. This inter-system handoff assumes significance for seamless communication without call being dropped. So in this seamless communication, when strength of signal of one system goes down in the mean time the signal of another system reaches high. So call will be handed over to another system without any interruption. But if the mobile station moves in overlapped region of intersystem again and again, then the rate of handoff become very high and this causes an affect called as ping pong. In this work, there is implementation of Fuzzy System based and Neural Network based ping pong avoidance algorithm for intersystem handoff. In this a comparison between two systems is also presented. This work is to find out the optimality of intelligent systems such as fuzzy and neural networks in saving the cost of handover between two networks and finding the critical factors and their sensitivity in determining the requirement of handoff.
