Existing range-based localization algorithms are superior only when a high accuracy node-to-node measured distance exists. This assumption is actually difficult to satisfy with current ranging techniques used in tiny sensor nodes. Meanwhile, range-free localization algorithms work independently of ranging error but can only produce limited node accuracy. In(More)
SUMMARY A combination of Proper Orthogonal Decomposition (POD) and In Situ Adaptive Tabulation (ISAT) is proposed for the representation of parameter-dependent solutions of coupled partial differential equations (PDE). The accuracy of the method is easily controlled by open parameters that can be adjusted according to the users needs. The method is tested(More)
