    Focuses on the problem of coordinating the movements of a cooperative team in an environment, and proposes an approach that takes inspiration from the laws of physics. The idea is to have the movements of team members driven by abstract force fields, generated by team members themselves and propagated via some embedded infrastructure. A globally coordinated and self-organized behavior in team memb... View full abstract»

    In the development of agent applications, interactions are an important issue, which must be faced with appropriate methodologies and tools. A separation of concerns between the agents and their interaction needs is helpful in the designing and the implementation phases of the life cycle. In this paper we propose XRole, a system that helps in dealing with interactions. It is based on the definitio... View full abstract»

    Event-based communication models provide interesting properties for distributed systems such as asynchronism and type-based selection mechanisms. The Comet middleware we developed proposes such an event-based communication model as foundation. From this canonical model, we show how to build more conventional bidirectional and synchronous interactions with extended features such as implicit type-ba... View full abstract»

    Peer-to-peer systems recently captured the attention of practitioners and researchers as they provide an attractive alternative to client-server architectures. Peer-to-peer enables the creation of massively distributed networks of data repositories that can be setup and discarded easily according to applicative needs. Nevertheless, the current popularity of these systems is due mostly to their use... View full abstract»

    The home is an eternal, heterogeneous, distributed computing environment which must be secure and reliable. Computers and embedded processors in the home are all different shapes and sizes and ages. Hence the home poses one of the most challenging environments for co-operative programming. We envisage that control software is introduced into the home by four different methods varying from embedded... View full abstract»

    In Marc Weiser's (1991) vision of ubiquitous computing, users are located in an environment with potentially thousands of computers around them. Many capabilities of these smart devices can be used only by augmenting the users' senses with a kind of "sixth electronic sense". Thus, ubiquitous computing and wearable computing complement one another. However, the architectural styles for them are qui... View full abstract»

    Configuring distributed applications at deployment time requires the introduction of high-level features such as transaction and synchronization into application code. Component models like CORBA Component Model (CCM) or Enterprise Java Beans (EJB) allow programmers to declare in deployment descriptors which services have to be plugged into components. However, these approaches do not allow a dyna... View full abstract»

    The Differentiated Services (DiffServ) model is a potential solution for providing quality of service (QoS) on the Internet. In this paper, we propose a scalable architecture that fulfills the design philosophy of the DiffServ model. In contrast to other existing architectures, our proposed architecture puts complexity on edge routers so that core routers do not need to support any specific functi... View full abstract»

    We propose a layered architecture based on the separation of two concerns - computation and coordination - as a means of achieving higher levels of auto-adaptability. This separation makes it possible for adaptation to be enforced through the reconfiguration of the system in terms of the mechanisms that coordinate interactions, superposing connectors among components of the system without intrudin...

    In many Internet scale replicated system, not all replicas can be dealt with in the same way, since some will be in greater demand than others. In the case of weak consistency algorithms, we have observed that updating first replicas having most demand, a greater number of clients would gain access to updated content in a shorter period of time. In this work we have investigated the benefits that ... View full abstract»

    The separation of concerns, as a conceptual tool, enables us to manage the complexity of the software systems that we develop. Such was the intent behind the OORAM. When the idea is taken further to software packaging, greater reuse and maintainability are achieved. There have been a number of approaches aimed at modularizing software around the natural boundaries of the various concerns, includin... View full abstract»

    Research on aspect oriented programming and specification has highlighted the need to deal with cross-cutting concerns that involve more than one implementation level component. Distributed systems are an important application area where cross-cutting concerns frequently emerge. We present a novel way of composing distributed behavior from reusable superposition steps. The steps are given in a joi... View full abstract»

    In distributed applications, a group of multiple processes are cooperating where multimedia messages are exchanged among the processes. The multimedia objects are longer than traditional messages and are structured. If messages transmitted in a network are causally delivered by using traditional group protocols, computation and communication overheads are increased due to the large size of multime...
