In distributed and high performance applications it it is necessary to discover the aggregate resource capabilities of the collaborating peers. Another requirement of these applications is to locate the resources meeting the given aggregate search criteria. In this paper we present an unstructured peer-to-peer approach to aggregate node selection for resource management. Our objective is to efficiently calculate the aggregate value and search the aggregate node whose attribute matches or falls in the proximity of this value. Our contribution also includes the inclusion of an explicit network for aggregate query routing. We evaluated our protocol for accuracy, efficiency and communication cost through detailed simulations. Copyright 2008 ACM.

Resources allocation and scheduling has been recognised as an important topic for business process execution. However, despite the proven benefits of using Cloud to run business process, users lack guidance for choosing between multiple offering while taking into account several objectives which are often conflicting. Moreover, when running business processes it is difficult to automate all tasks. In this paper, we propose three complementary approaches for Cloud computing platform. On the other side, elastic computing, such as Amazon EC2, allows users to allocate and release compute resources (virtual machines) on-demand and pay only for what they use. Therefore, it is reasonable to assume that the number of virtual machine is infinite while the number of human resources is finite. This feature of Clouds has been called "illusion of infinite resources". In this paper, we design an allocation strategy for Cloud computing platform taking into account the above characteristics. More precisely, we propose three complementary hi-criterion approaches for scheduling business process on distributed Cloud resources.

Utility computing was a vision stated more than 40 years ago. It refers to the idea that computing resources and services can be delivered, utilized, and paid for as utilities such as water or electricity. The recent emergence of cloud computing is making this vision realizable. Examples of efforts in this area include Infrastructure as a Service (IaaS) providers like Amazon EC2 and Software as a Service (SaaS) providers like Google AppEngine and Microsoft Azure. More recently, there is a growing interest in the use of cloud computing for scientific computing, as evidenced by a large-scale funded project like Magellan, and new workshops. Copyright 2010 ACM.

distributed software systems are the basis for innovative applications (e.g., pervasive computing, telecommunication services, and Grid utility services). The key for achieving survivable and maintainable distributed systems is agility because otherwise the non-deterministic nature of distribution would leave the system uncontrollable. Survivability is defined as the capability of a service to fulfill its mission in a timely manner, even in the presence of attacks, failures, or accidents. Because of the severe consequences of failure, organizations are focusing on service survivability as a key risk management strategy for business processes. There are three key survivability properties: resistance, recognition, and recovery. Recovery, a hallmark of survivability, is the capability to maintain critical components and resource during attack, limit the extent of damage, and restore full services following attack. Exception handling is a way to deals with the recovery aspect of survivability. business Process Execution Language for Web Services (BPEL) has been proposed for formal specification of business processes and interaction protocols. BPEL defines an interoperable integration model that facilitates expansion of automated process integration in both intra- and inter-corporate environments. A business process description requires the specification of both the normal flow and the possible variations due to exceptional situations that can be anticipate and monitored. This paper bridges the analysis of business process survivability and its recovery aspect in terms of exception handling in the context of BPEL. We propose an integrated approach to engineer a survivable distributed system through dynamic regeneration of work/low specifications when the system encounters attacks and failures.

The development of Ambient Intelligence (AmI) will radically transform our everyday life and social representations. These transformations will notably impact the working environment. The objective of this paper is to offer a first survey of the main ethical issues raised by the development of intelligent working environments (IWEs). It especially focuses on the capacity of such environments to collect and handle personal medical data. The first section describes the features of intelligent environments in general and presents some of their applications at the workplace. The second section of this paper points out some of the main ethical issues raised by these environments and their capacity to collect and handle medical data. The third and final section attempts to offer some elements of reflection regarding the ethical principles that should guide the development of IWEs in the future.
