The advent of widespread distributed computing environment, such as information systems and computational grids computing has enabled a new generation of applications that are based on seamless access, aggregation and interaction. The dramatic side of the story is a strong presence of the plea that those decentralized Grids are potentially affected by a number of primitives derived from their a...

The proliferations of Internet technologies, services and devices have made the current network system designs and management tools incapable of designing reliable, secure networked systems and services. The complexity of current systems had led researchers to consider alternative designs and management techniques that are based on strategies used by biological systems to deal with complexity, ...

We introduce a formal model of cost-sensitive fault remediation, derive an exact algorithm for solving the special case of deterministic observations, and demonstrate it on two example problems. This effort is part of two self-healing software projects that attempt to use collected data for better decision making in emerging autonomic systems.

INTRODUCTION Cognitive informatics (CI) is an emerging discipline that studies the natural intelligence and internal information processing mechanisms of the brain, as well as the processes involved in perception and cognition (Chan, Kinsner, Wang, & Miller, 2004; Kinsner, Zhang, Wang, & Tsai, 2005; Patel, Patel, & Wang, 2003; Wang, 2002a, 2003, 2004, 2006, 2007; Wang & Wang, 2006; Wang, Johnst...

In this paper we describe the ANS system, which is middleware used to provide autonomic management of ubiquitous systems.

From the biology’s point of view, pollination is an important step in the reproduction of seed plants. From our point of view, pollination is a promising and novel, biological paradigm for future dependable and self-managing computing systems. This estimation is based on the characteristics the pollination process between plants and insects im-

Cloud computing is the cluster of autonomic computing, grid computing and utility computing. Cloud providers are there to rescue their customers from the problem of dynamism. The providers focus on resource sharing and in improving the performance. Energy consumption is the major factor to degrade the performance. Reducing energy sprawl will bloom the performance. This paper delineates the diff...

This paper presents the design of TOBIT, an infrastructure to support Web-based simulations. TOBIT provides a subnet grid, which is partitioned into web server tier, database server tier and simulation server tier. This grid is self-managed through the simulation manager (SimMan) extended from the Oracle Grid Control [3]. TOBIT is currently being used to support autonomic computing of two web-b...

As many of the large-scale scientific applications executed on Grids are expressed as complex scientific workflows, workflow management has emerged as one of the most important Grid services in past few years. Scientific workflows can be defined as the aggregation of Grid application services, which are executed on distributed Grid resources in a well defined order to satisfy the specific requi...
