A light-weight component model for peer-to-peer applications

Abstract.We have recently witnessed a growing interest in self organising systems, both in research and in practice. These systems re-organise in response to new or changing conditions in the environment. The need for self organisation is often found in mobile applications; these applications are typically hosted in resource-constrained environments and may have to dynamically reorganise in response to changes of user needs, to heterogeneity and connectivity challenges, as well as to changes in the execution context and physical environment. We argue that physically mobile applications benefit from the use of self organisation primitives. We show that a component model that incorporates code mobility primitives assists in building self organising mobile systems. We present SATIN, a lightweight component model, which represents a mobile system as a set of interoperable local components. The model supports reconfiguration, by offering code migration services. We discuss an implementation of the SATIN middleware, based on the component model and evaluate our work by adapting existing open source software as SATIN components and by building and testing a system that manages the dynamic update of components on mobile hosts.

Abstract. This paper presents a distributed middleware architecture based on a service-oriented approach, to manage high volume sensor events. Event management takes a multi-step operation from event sources to final subscribers, combining information collected by wireless devices into higher-level information or knowledge. An event correlation service provides sophisticated event filtering, aggregation and correlation over time and space in heterogeneous network environments. An experimental prototype in the simulation environment with real world data produced by the Active BAT system is shown.

“…For example, Gravity [6] is a component model built on top of the Open Services Gateway Initiative (OSGi) Framework [7] (OSGi is a commercial framework for the Java platform which allows providers to deliver services to consumer devices attached to a residential network and to manage those devices remotely). P2PComp [8] is a lightweight service-oriented component model for mobile devices, which is also built using OSGi; it provides location independent synchronous and asynchronous communication between components. The Dynamically Programmable and Reconfigurable Software (DPRS) architecture [9] is a component-based design for dynamically programmable and reconfigurable systems.…”
