Survivability Analysis with Border Effects for Power-Aware Mobile Ad Hoc Network

Network survivability is an attribute that network is continually available even if a failure occurs, and is regarded as one of the most important concepts to design fault-tolerant computer networks. In the previous work, we evaluate a power aware mobile ad hoc network (MANET) by using a Markov regenerative process (MRGP). It does take account of the variability in power level, which is caused by the possible low battery state in each node, but implicitly assumes that the scaled border effects can be ignored in modeling. In this paper, we revisit a power-aware MANET model taking account of border effects, and quantify the network survivability more accurately.
