In modern computers the processors synchronization problem arises. In array processors the clock skew may be significant. The last may lead to the incorrect work of parallel algorithms. The problem of a clock skew in high-speed systems is so much important that a modern VLSI are often supplied by several phase locked loops, placed on one chip. In this case the phase locked loops can be used for creating a distributed system of generators. Here the discrete phase locked loops is considered.

An overview of recent experiences in developing and analyzing distributed problem solving methods for applications in sensor networks was presented. The difficulties in developing large-scale, distributedsensor networks were also discussed. Simple distributed algorithms using limited local information and communication were found to be capable for distributed problem solving in distributedsensor networks.

This paper discusses a concept of flexible distributedsystems and an agent-based architecture for them. Then, an agent-based framework for developing such a flexible distributed system named ADIPS framework is proposed. This consists of distributed agent work places, agent repositories and support tools. Finally, agent-based flexible applications developed using the ADIPS framework are demonstrated.

This paper addresses the low-power design of distributedsensor networks for intelligent measurement. We present a method for system clock optimization based on behavioural requirements and a power-saving mode. Essentially, the suggested approach minimizes the power consumption and provides longer battery lifetimes. In addition, the method improves the electromagnetic compatibility which is crucial for cubic-millimeter nodes. The zero-power theme goes on with passive reflector communication systems. We discuss an approach for zero-power orientation of corner-cube retroreflectors.

The goal of this paper is to review and classify the different approaches to search in peer-to-peer networks. We then describe the approach implemented in JXTA search. JXTA is an open peer-to-peer network environment. JXTA search is a network of hubs that index the content of a peer-to-peer network. Finally, we propose an organization of the JXTA search hubs, which reduces the storage and communication requirements between the hubs.

The paper presents the concept of a smart multifunctional low-power camera for 3G mobile communicators and Personal Digital Assistants. The device is composed of an ultra low-power image sensor featuring a large intra-scene dynamic range and a high sensitivity, so as to ensure proper image acquisition under possibly severe illumination conditions, as encountered in mobile. Further embedded functionalities encompass low-power still image compression, and low-power face authentication for secured access control.

This paper focuses on a super distributed energy system that consists of a number of dispersed generation systems such as fuel cells, micro gas-turbines, and so on. The behavior of a customer with a dispersed generation system is modeled on the Ising spin model in statistical mechanics. The validity of the modeling of the behavior of a customer is verified based on the Monte Carlo simulation. The feasibility of autonomous distributed control using vicinity information is also investigated on the basis of stability analysis of the Hopfield neural network model.

distributed embedded computing differs itself from traditional computing by its great heterogeneous, dynamic and non-standardized nature. This requires more powerful technologies that enable us to develop systems with more flexible architectures. Workflow technology achieves this by managing collaborations between system elements explicitly. However, in distributed embedded environment, current workflow systems could not be used directly for the reason of very different supporting platforms. distributed resource management technology could bridge this gap. In this paper, we classify distributed embedded systems into fundamental types of elements representing both basic structural components and relationship between them. Then we present an architecture based on the integration of workflow and DRM systems according to our classification and analyze important coordination mechanisms among workflow, DRM systems and other elements. Ideas, such as utilizing function model to customize and optimize the design of systems, also reflect important principles to design distributed embedded systems.
A distributed high-performance routing architecture is presented, and stochastic Petri nets are employed to model and evaluate it. To solve the state explosion problem, a segmentation iteration algorithm is given, and...
