an srn based approach for performance evaluation of network layer in mobile ad hoc networks

The application of mobile ad hoc networks in emergency and critical cases need a precise and formal performance evaluation of these networks. traditional simulators like ns-2 and opnet usually need considerable time for producing high-level performance metrics. also, there is no theoretical background for mentioned simulators. in this research, we propose a framework for performance evaluation of mobile ad hoc networks. the presented framework points to the network layer of manets using stochastic reward nets modeling tool as a variation of generalized stochastic petri nets. based on the decomposition technique, it encompasses two separate models: one for analysis of data flowing process and the other for the modeling routing process. for verifying the presented model, an equivalence-based method is applied. the proposed model has been quantified by deriving two performances metrics as the packet delivery ratio and end-to-end delay. the results show the obtained values from the presented model well matched to the values generated from the ns-2 simulator with considerable shorter execution time.
