Sancheng Peng, Weijia Jia, Guojun Wang · 2008
We propose a quantitative model to evaluate survivability in large-scale Mobile Ad-hoc NETworks (MANETs). We present modeling for survivability regarding various types of faults and connection states for mobile terminals through continuous time Markov chain. We evaluate the survivability of segment-by-segment routing and multipath routing, introduce reliability theory to perform analysis and quantitative evaluation of survivability and provide a theoretical evidence for improving survivability performance. The proposed scheme is a powerful analytical model for deriving network performance much more easily than a simulation-based approach. Numerical validation shows that the proposed model can obtain a better evaluation result on the survivability of large-scale MANETs.
