Toward Highly Dependable Power-Aware Mobile Ad Hoc Network–Survivability Evaluation Framework

Network survivability is an attribute that network is continually available even if a communication failure occurs, and is regarded as one of the most important concepts to design dependable computer networks. In the existing work, a power-aware mobile ad hoc network (MANET) is described by a Markov regenerative process, and takes account of the variability in power level, which is caused by the possible low-battery state in each communication node. However, it implicitly ignores effects by the so-called border effects, and lacks the reality in modeling. In this paper, we revisit a power-aware MANET model taking account of border effects and quantify the network survivability more accurately.
