In vehicular ad-hoc networks (VANETs), safety messages are exchanged among vehicles and between infrastructure to ensure passengers' efficiency in traffic. The source authentication as well integrity checking of these very necessary for a receiver. Based on certificateless cryptography (CLC), some state-of-the-art signature schemes have been proposed address these. Although they fulfill the requirements privacy, not efficient with respect performance. Bilinear pairings map-to-point hash...

This brief addresses the adaptive control problem for a class of pure-feedback systems with nonaffine functions possibly being nondifferentiable. Without using mean value theorem, difficulty design is overcome by modeling appropriately. With help neural network approximators, an controller developed combining dynamic surface (DSC) and minimal learning parameter (MLP) techniques. The key features our approach are that, first, restrictive assumptions on partial derivative removed, second, DSC...

Wide-area damping controller (WADC) is a very effective tool to damp out the low-frequency oscillation in wide-area power systems. However, WADC needs communication networks transmit remote signals; hence, network-induced delay and packet dropout are inevitably introduced of measurement systems (WAMS). In order effectively compensate dropout, this paper, new dynamic (WADDC) designed. Firstl discrete-time model system with random delay, external disturbance established. Then, WADDC based on...

Vehicular ad-hoc networks (VANETs) enable vehicles to exchange safety information with the surrounding and infrastructure in order ensure efficiency traffic management. Recently however, come from different manufacturers therefore use protocols for transmission of messages. As a result, communication among become heterogeneous. Because this, VANETs face problems related security performance. To address some heterogeneous vehicular communication-based schemes have been proposed. However, they...

Supplying electric energy in remote areas presents a significant challenge due to their relatively far distance from the main grid, low population density, high infrastructure costs, and limited resource. One promising solution this is isolated hybrid microgrids (MGs) which can deliver reliable electricity support economic development.
