It is now technically feasible to interconnect large autonomous software units (autonomous components) being (almost) complete applications. It brings new quality to users

A federated database system (FDBS) is a collection of cooperating database systems that are autonomous and possibly heterogeneous. In this paper, we define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures

In a recent Physical Review Letters paper, Vicsek et. al. propose a simple but compelling discrete-time model of n autonomous agents fi.e., points or particlesg all moving in the plane with the same speed but with dierent headings. Each agent's heading is updated using a local rule based

Abstract. Ensembles of autonomic components are a novel software engineering paradigm for development of open-ended distributed highly dynamic software systems (e.g. smart cyber-physical systems). Recent research centered around the concept of ensemble-based systems resulted in design

Abstract: In this paper, a dynamically customizable framework for supporting the autonomy of components is introduced. To implement autonomous components, the framework adopts an approach to repacking existing components. By combining Agent technology into components, the framework can customize

For wireless cellular communication systems, one seeks a simple effective means of power control of signals associated with randomly dispersed users that are reusing a single channel in different cells. By effecting the lowest interference environment, in meeting a required minimum signal-to-interference ratio of p per user, channel reuse is maximized. Distributed procedures for doing this are of special interest, since the centrally administered alternative requires added infrastructure, latency, and network vulnerability. Successful distributed powering entails guiding the evolution of the transmitted power level of each of the signals, using only local measurements, so that eventually all users meet the p requirement. The local per channel power measurements include that of the intended signal as well as the undesired interference from other users (plus receiver noise). For a certain simple distributed type of algorithm, whenever power settings exist for which all users meet the p requirement, we demonstrate exponentially fast convergence to these settings.
