The two-parameter phase space in certain nonlinear system is investigated and the chaotic region of parameters are measured to show its chaotic properties. Within the chaotic parameter region, the complete synchronization, phase synchronization and parameters estimation are discussed in detail by using adaptive synchronization scheme and Lyapunov stability theory. Two changeable gain coefficien...

Multi-core architectures are becoming mainstream, permitting increasing on-chip parallelism through hardware support for multithreading. Synchronization, especial finegrain synchronization, is essential to the effective utilization of the computational power of high-performance large-scale multi-core architectures. However, designing and implementing fine-grain synchronization in such architect...

Synchronization is a ubiquitous feature in many natural systems and nonlinear science. This paper studies the synchronization complete network consisting of n nodes. Each node connected to all other nodes by coupling represented an ordinary differential system FitzHugh-Nagumo type (FHN) which can be obtained simplifying famous Hodgkin-Huxley model. From this network, sufficient condition on str...

In this work, a new synchronization was achieved between two different chaotic systems in behavior (Chua-Lorenz) by coupling them together with factor (k) and it noted that Lorenz's completely transformed Chua's changing the value of factor. It is observed when values are zero, asynchronous, its 100, there partial synchronization, while 100000, so we get perfect synchronization. Where possible ...

In this paper we propose two systems for achieving synchronization in asynchronous multi-user chaos-based DS-CDMA. For the first system, synchronization process is realized thanks to a binary code used as an additive pilot sequence to the spreaded signal. Gold sequences are used as pilot signals for the different users to accomplish the synchronization. For the second synchronization system, th...

Existence of different kinds of synchronizations, namely anticipatory, complete and lag type synchronizations (both exact and approximate), are shown to be possible in timedelay coupled piecewise linear systems. We deduce stability condition for synchronization of such unidirectionally coupled systems following Krasovskii-Lyapunov theory. Transition from anticipatory to lag synchronization via ...

Time synchronization is an important aspect in Wireless Sensor Networks (WSN). They make wide use of synchronized time in many contexts like data fusion etc. Without synchronizing, the sensed data will lose valuable context. Existing time synchronization methods cannot be used with such wireless networks as at the time of their designing such networks were not foreseen. So either present synchr...

This work is concerned with the design and effects of the synchronization gains on the synchronization problem for a class of networked distributed parameter systems. The networked systems, assumed to be described by the same evolution equation in a Hilbert space, differ in their initial conditions. The proposed synchronization controllers aim at achieving both the control objective and the syn...

We investigate the route to synchronization in an ensemble of uncoupled chaotic oscillators under common noise. Previous works have demonstrated that, as the common-noise amplitude is increased, both chaotic phase synchronization and complete synchronization can occur. Our study reveals an intermediate state of synchronization in between these two types of synchronization. A statistical measure...

Various Time Synchronization protocols for a Wireless Sensor Network (WSN) have been developed since time synchronization is important in many timecritical WSN applications. Aside from synchronization accuracy, energy constraint should also be considered seriously for time synchronization protocols in WSNs, which typically have limited power environments. This paper performs analysis of promine...
