A secure and energy-efficient routing using coupled ensemble selection approach and optimal type-2 fuzzy logic in WSN
Published 2025-01-01“…The IT2FLS model dynamically adapts routing selections by means of assessing key parameters, consisting of dynamic accept as true with factors, node power ranges, course delays, and energy consumption fees, whilst the RSA algorithm exceptional-tunes the bushy common sense club features to make certain most beneficial cluster head choice and reliable multi-hop communication paths. Additionally, our proposed technique complements secure routing by means of efficaciously counteracting the effects of compromised nodes, for this reason maintaining community integrity. …”

Low-Frequency Admittance of Capacitor with Working Substance “Insulator–Partially Disordered Semiconductor– Insulator”
Published 2021-10-01“…The partially disordered semiconductor of the working substance of the capacitor can be, for example, a highly defective crystalline silicon containing point t-defects randomly (Poissonian) distributed over the crystal in charge states (−1), (0), and (+1), between which single electrons migrate in a hopping manner. It is assumed that the electron hops occur only from t-defects in the charge state (−1) to t-defects in the charge state (0) and from t-defects in the charge state (0) to t-defects in the charge state (+1).In this work, for the first time, the averaging of the hopping diffusion coefficients over all probable electron hopping lengths via t-defects in the charge states (−1), (0) and (0), (+1) in the covalent crystal matrix was carried out. …”

Published 2007-01-01“…According to the characteristics of multi-band orthogonal frequency-division multiplexing ultra-wideband(OFDM-UWB) system,a multiple access based on three-stage modulation(TSM-MA) was proposed.It combined multi-carrier code division multiple access(MC-CDMA) with orthogonal frequency division multiple access(OFDMA) and frequency hopping multiple access(FHMA),carried out the advantages of the three multiple access techniques.It reduced the multiple access interference and made full use of the available resource of the channel.The two-stage spread spectrum and two-stage frequency hopping were used to the TSM-MA for reducing the complexity of receiver.Simula-tion results showed that TSM-MA has obvious advantages in bit error rate(BER) performance over time frequency code multiple access(TF-MA) about 3 dB and lower complexity than that of TF-MA.…”
