Time synchronization is crucial in ad hoc networks. Due to the infrastructure-less and dynamic nature, time synchronization in such environments is vulnerable to various attacks. Moreover, time synchronization protocols such as IEEE 802.11 TSF (Timing Synchronization Function) often suffer from scalability problem. In this paper, we address the security and the scalability problems of time sync...

Since the idea of synchronizing chaotic systems was introduced by Pecora and Carroll[1] in 1990, chaos synchronization has received increasing attention due to its theoretical challenge and its great potential applications in secure communication,chemical reaction and biological systems[2]. Recently several different types of synchronizations have been proposed in the literature, for example, g...

A different manner of study synchronization between chaotic systems is presented. This done by using two forced coupled nonlinear circuits. The way coupling the under from those used in analysis chaos dynamical low dimensionality. and how to manipulate it, carried out through variation couplings calculating bifurcation diagrams. We observed that for rather larger values circuits it reached tota...

The quest to improve performance forces designers to explore finer-grained multiprocessor machines. Ever increasing chip densities based on CMOS improvements fuel research in highly parallel chip multiprocessors with 100s of processing elements. With such increasing levels of parallelism, synchronization is set to become a major performance bottleneck and efficient support for synchronization a...

The study of chaos can be introduced in several applications as: medical field, fractal theory, electrical circuits and secure communication, essentially based on synchronization techniques. The synchronization for chaotic systems has been extended to the scope, such as generalized synchronization, phase synchronization, lag synchronization, and even anti-synchronization (Pecora & Carroll, 1990...
