Performance Evaluation of the TSS Node Authentication Scheme in Noisy MANETs

This paper presents a description and performance evaluation of a threshold secret sharing (TSS) node authentication scheme in noisy mobile ad hoc networks (MANETs). The scheme can be used effectively in selfsecuring MANETs suffering from high packet-loss due to presence of noise and node mobility. In order to evaluate the performance of the TSS scheme in noisy MANETs, a number of simulations were carried-out to investigate the variation of the authentication success ratio against the threshold secret share for various node densities, node speeds, and noise-levels. Simulation results demonstrated that, for certain threshold secret share, presence of noise inflicts significant reduction in the authentication success ratio, while node mobility inflicts no or insignificant effect. The outcomes of these simulations are so important to facilitate efficient network security management.
