A NOVEL DV-HOP LOCALIZATION METHOD BASED ON HYBRID IMPROVED WEIGHTED HYPERBOLIC STRATEGY AND PROPORTIONAL INTEGRAL DERIVATIVE SEARCH ALGORITHM

A Novel DV-Hop Localization Method Based on Hybrid Improved Weighted Hyperbolic Strategy and Proportional Integral Derivative Search Algorithm

As a range-free localization algorithm, DV-Hop has gained widespread attention due to its advantages of simplicity and ease of implementation.However, this algorithm also has some defects, such as poor localization accuracy and vulnerability to network topology.This paper presents a comprehensive analysis of the factors contributing to the inaccura

FFT-based interface decohesion modelling by a nonlocal interphase

Abstract In this paper, two nonlocal approaches to incorporate interface damage in fast Fourier transform (FFT) based spectral methods are analysed.In FFT based methods, the discretisation is generally non-conforming to the interfaces and hence interface elements cannot be used.This limitation is remedied using the interfacial band concept, i.e., a
