GSPN-based model to evaluate the performance and securi tytradeoff in Ad-hoc network

The tradeoff between performance and security has always been a key issue in ad-hoc network research, and many optimization schemes have been proposed by the researchers. However, there has been no a unified quantitative criterion to compare the performance and benefits of these schemes. This paper proposes a widely used method to evaluate performance and security tradeoff in ad-hoc networks. Firstly, GSPN was used to construct the data transmission model within and between nodes. Then the model is abstracted and refined by Petri net. Finally, combining with Continuous-time Markov Chain (CTMC) the method calculates the performance, security and benefits. In this way, the different strategies can be incorporated into the unified evaluation framework, the optimal equilibrium solution can be selected according to the different environments and requirements. Simulations are carried out on data encryption algorithms, key size and strategy selections, which provides theoretical basis and data support to this model for the effective utilization of network resources. © 2020, Jilin University Press.
