A Simulation Approach to Quantify Network Survivability on MANETs

The network survivability is an emerging requirement for highly reliable communication services in mobile ad hoc networks (MANETs) and is defined as the probability that the network can keep to be connected even under node failures and DoS attacks. Although some analytical formulas on the quantitative network survivability have been proposed, they have not been validated yet by comparing with the exact value of network survivability in a comprehensive way. In this paper, we revisit the existing lower and upper bounds of network survivability by taking account of border effects in a network communication area and develop a simulation model. It is shown through simulation experiments that the analytical solutions often fail in the exact network survivability measurement.
