Changes and Dependencies of Compound Hot–Dry Extremes in China During 1961–2022

Advances in Meteorology, Volume 2026, Issue 1, 2026.
Compound hot–dry extremes have attracted widespread attention owing to their disastrous impacts on human society and natural ecosystems. Based on the daily maximum temperature and precipitation observations, the spatiotemporal distribution and long‐term variations of summer compound hot–dry days (CHDDs) and compound hot–dry events (CHDEs), as well as ...

A Systematic Review of VANET Routing Protocols for Intelligent Transport Systems (ITSs)

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
The swift improvement of wireless communication technology has aided the creation of vehicular ad hoc networks (VANETs) as a revolutionary option for the realization of intelligent transportation systems (ITSs). VANETs facilitate seamless communication between vehicles and infrastructure (V2I) and among the vehicles themselves (V2V). These networks can

Enhancement in Performance Metrics for Mobile Ad Hoc Networks (MANETs) Using Hybrid Ant Lion Optimization (HALO) Algorithm

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
Mobile ad hoc networks (MANETs) are constantly confronted with issues including variable quality of service (QoS) metrics, route optimization, and flexible topology. Here, a novel hybrid ant lion optimization (HALO) algorithm is proposed that integrates the cooperative foraging behavior of ant colonies from ant colony optimization and the hunting ...
