Survivability Analysis Under Non-Uniform Stochastically Dependent Node Damages

In this paper, the authors 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. Consider a wireless sensor network of N nodes. They assume that locations of the nodes are known. The sensor nodes perform measurements over a sensor field.
