Performance Analysys In Impact Of Trust Based Security Association And Mobility In Manet

Abstract

Trust models in the literature of MANET’S commonly postulate that packets have different security requisites. Afore a node forwards a packet, if the receiver trust level does not meet the packet’s requisite level, then the recipient must perform certain security modality procedures, such as re-authentication. We present in this paper an analysis of the epidemic broadcast delay in such context. The network mobility and trust models presented in this paper are quite generic and sanction us to obtain the delay component induced only by the security modalities along a path. Numerical results obtained by simulations withal corroborate the precision of the analysis. In particular, we can observe from both simulations and analysis results that, for immensely colossal and sparsely connected networks, the delay caused by security modalities is diminutively minuscule compared to the total delay of a packet. This additionally betokens that parameters like network density and nodes velocity rather than any trust model parameter, have more impact on the overall delay.
