Survivability analysis under non-uniform stochastically dependent node damages

Abstract

In this paper, we analyze survivability of a wireless sensor network under a non-uniform damage model. The analysis assumes statistically dependent damages or node failures. Specifically, the damage process is represented by a non homogeneous Poisson-Boolean model. Network traffic surviving the damage process is analyzed using survivability measures like expected number of surviving node pairs. Numerical results illustrate the analysis.
