In cellular communications the transfer of calls, or handoff, between the base stations, and efficient use of resources, or channel allocation schemes are essential features. The capabilities of Petri nets (PN) are used as a novel approach in the analysis of handoff and dynamic channel allocation (DCA) problems. The generalized stochastic Petri net (GSPN) models are obtained and analyzed as continuous time Markov chains derived from the reachability trees. Solution of the Markov chain results in performance indicators which show the impacts of different algorithms on the system behavior.
