This paper aims towards synchronization of Bhalekar-Gejji chaotic system and its application to secure communication. Synchronization is achieved using suitable nonlinear active control (NAC) scheme. Proposed synchronization is used to achieve secure communication using NAC. For secure communication, the information signal is masked with one of the state of chaotic system at transmitter end and...

Synchronization expressions are deened as restricted regular expressions that specify synchronization constraints between parallel processes and their semantics is deened using synchronization languages. In this paper we survey results on synchronization languages, in particular various approaches to obtain an exact characterization of this language class using closure properties under a set of...

In this paper, synchronization analysis is investigated for an complex networks with time delay. It is assumed the nodes in the network to be nonidentical. In order to achieve cluster synchronization, this paper uses an adaptive controller on each node, by utilizing the Lyapunov stability theory, a new and useful synchronization criteria are obtained, which guarantee the complex networks under ...

We report experimental and numerical results on noise-enhanced synchronization of two coupled chaotic oscillators. Enhanced synchronization is achieved through superimposing small-amplitude Gaussian noise on a common system parameter of the two chaotic oscillators. A resonancelike behavior is found: at an optimum level of noise, maximum synchronization is attained. The simulations show that the...

The time synchronization is an major problem for Wireless sensor networks. There have been many research works about time synchronization in Wireless sensor network in the literature and so many methods and protocols are proposed. Many applications of sensor networks required local clocks to be synchronized for precision but different sensor network required different properties. This paper rev...

Synchronization of identical chaotic systems subjected to common noise has been the subject of recent research. Studies on several chaotic systems have shown that, the synchronization is actually induced by the non-zero mean of the noise, and symmetric noise with zero-mean cannot lead to synchronization. Here it is presented that synchronization can be achieved by zero-mean noise in some chaoti...

Synchronization is often necessary in parallel computing, but it can create delays whenever the receiving processor is idle, waiting for the information to arrive. This is especially true for barrier, or global, synchronization, in which every processor must synchronize with every other processor. Nonetheless, barriers are the only form of synchronization explicitly supplied in OpenMP, and they...

Physical-layer Network Coding (PNC) makes use of the additive nature of the electromagnetic (EM) waves to apply network coding arithmetic at the physical layer. With PNC, the destructive effect of interference in wireless networks is eliminated and the capacity of networks can be boosted significantly. This paper addresses a key outstanding issue in PNC: synchronization among transmitting nodes...

As multiprocessors scale beyond the limits of a few tens of processors, they must look beyond traditional methods of synchronization to minimize serialization and achieve the high degrees of parallelism required to utilize large machines. By allowing synchronization at the level of the smallest unit of memory, ne-grain synchronization achieves these goals. Unfortunately, supporting e cient ne-g...

Remote file synchronization, which is used to synchronize two versions of a file, is a primitive for a lot of network applications. The existing approaches can be divided into two categories: single round synchronization protocols and multiround synchronization protocols. Typical single round protocols include sliding-block based synchronization protocols like rsync and chunking based synchroni...
