Efficient mobility management involves micromobilityprinciples. The performance of the Hierarchical MobileIPv6 (HMIPv6) protocol, a representative micro-mobilityapproach, is affected by the Mobility Anchor Point (MAP)selection. In this paper, we prop

The upcoming migration of satellite services to higher bands, namely, the Ka‐ and Q/V‐bands, offers many advantages in terms of bandwidth and system capacity. However, it poses challenges as propagation effects introduced by the various atmospher

This paper presents a novel model for prediction of site diversity system performance in millimeter-wave satellite communications. The model predicts the joint exceedance probability of rain attenuation based on a new family of Archimedean copulas, c

A novel prediction model of the joint exceedance probability of rain attenuation in Earth–satellite site diversity systems based on the Gaussian copula is presented. The proposed model is based on a number of experimental data of two-site diversity

The use of copulas decreases and almost vanishes the dependence of stochastic synthesizers from theoretical distributions, since empirical distributions can also be used. Therefore, in this correspondence, a novel rain attenuation time series synthes

The time synchronization in wireless sensor networks (WSN) is a well-known issue. One of the approaches to the problem is by using off-line algorithms, meaning that the exchange of signaling messages for synchronization of individual clocks does not

The paper addresses the time synchronization of multiple wireless ECG sensors. The approach to the problem is practical, by conducting laboratory experiments on an artificially generated signal. The performed analyses show that the sampling frequency
