Barrier resilience
Barrier resilience is an algorithmic optimization problem in computational geometry motivated by the design of wireless sensor networks, in which one seeks a path through a collection of barriers (often modeled as unit disks) that passes through as few barriers as possible. == Definitions == The barrier resilience problem was introduced by Kumar, Lai & Arora (2005) (using different terminology) to model the ability of wireless sensor networks to detect intruders robustly when some sensors may become faulty.
