This paper introduces a new radio resource management technique based on distributed dynamic channel assignment, and sharing load among Access Points (AP). Deploying wireless LANs (WLAN) on a large scale is mainly affected by reliability, availability and performance. These parameters will be a concern for most managers who want to deploy WLANs. In order to address these concerns, a new radio r...

The IEC 61850 standard originally was developed for the substation automation. During the past years it was adapted for the integration of distributed energy resources into communication networks, however, with specific requirements. Many small and midsize manufacturers are using, as controllers, a big variety of different microprocessors with limited performances. Such controllers need an inte...

Distributed generation (DG) technologies, such as gas-fired reciprocating engines and microturbines, have been found to be economically beneficial in meeting commercial-sector electrical, heating, and cooling loads. Even though the electric-only efficiency of DG is lower than that offered by traditional central stations, combined heat and power (CHP) applications using recovered heat can make t...

In a distributed clustering algorithm introduced by Coffman, Courtois, Gilbert and Piret [1], each vertex of Z receives an initial amount of a resource, and, at each iteration, transfers all of its resource to the neighboring vertex which currently holds the maximum amount of resource. In [4] it was shown that, if the distribution of the initial quantities of resource is invariant under lattice...

There exist a large number of computational resources in the domain of scientific and engineering computation. They are distributed, heterogeneous and often too restricted in computability for oneself to satisfy the requirement of modern scientific problems. To address this challenge, this paper proposes a component-based architecture for managing and accessing legacy applications on the comput...

We develop a notion of spatial-behavioral typing suitable to discipline interactions in service-based systems modeled in a distributed object calculus. Our type structure reflects a resource aware model of behavior, where a parallel composition type operator expresses resource independence, a sequential composition type operator expresses implicit synchronization, and a modal operator expresses...

Many systems consist of a set of agents which must acquire exclusive access to resources from a shared pool. Coordination of agents in such systems is often implemented in the form of a centralized mechanism. The intervention of this type of mechanism, however, typically introduces significant computational overhead and reduces the amount of concurrent activity. Alternatives to centralized mech...

This chapter illustrates how challenging problems in geovisualization may be solved by harnessing activities on a distributed scale: bringing a range of people, a range of data and a range of resources to bear on the problem. The discussion is framed around a scenario of environmental crisis management – a flood emergency – which is typical of the challenges that only a distributed approach can...
