Investigation of handover in distributed control channel allocation (DCCA) for microcellular radio systems

After a brief review of previous studies of dynamic channel allocation (DCA), the concept and the operation principles of distributed control channel allocation (DCCA) is described. This system can adapt to local traffic density and has good potential to reduce the number of call handovers in a microcellular system. It is shown by computer simulations that significant reductions in the number of handovers and forced terminations of calls can be achieved, in comparison to autonomous DCA techniques
