Generalized Stochastic Petri Nets in Performance Evaluation for Queueing Networks
نویسندگان
چکیده
Markovian queueing networks may be modeled by generalized stochastic Petri nets. The simulation of a model in a properly chosen simulator provides information on the performances of the actual system, mainly in case that the analytical study is intricate. After presenting some general notions on queueing networks and on generalized stochastic Petri nets, this paper points out the PN Toolbox for MATLAB, an instrument for modeling and simulating several types of Petri nets. The comparison of results obtained through simulation to the analytical ones for a certain model prove the usefulness of this software package for performance evaluation.

Modeling and Performance Evaluation of Energy Consumption in S-MAC Protocol Using Generalized Stochastic Petri Nets
One of the features of wireless sensor networks is that the nodes in this network have limited power sources. Therefore, assessment of energy consumption in these networks is very important. What has been common practice has been the use of traditional simulators to evaluate the energy consumption of the nodes in these networks. Simulators often have problems such as fluctuating output values i...
