MODELING RESOURCE-MANAGEMENT IN CELLULAR-SYSTEMS USING PETRI NETS

Modeling and analysis tools are essential for design and evaluation of complex systems, This is particularly true for cellular systems, wher e, for instance, a variety of handoff, channel allocation, and data-tr ansmission algorithms have been proposed. In this paper, the capabilit ies of Petri nets (PN's) are used as a novel approach in the analysis of handoff, dynamic channel allocation (DCA), and cellular digital pac ket data resource management problems, The generalized stochastic PN ( GSPN) models are obtained and analyzed as continuous-time Markov chain s (MC's) derived from the reachability graphs. Solution of the MC resu lts in performance indicators, which show the impacts of different alg orithms on the system behavior.
