RUNES. The range of devices involved in networked embedded environments inevitably leads to significant complexity in appropriately configuring, deploying, and dynamically reconfiguring the software. There is therefore a need for dedicated middleware platforms addressing networked embedded systems, with abstractions that can span the full range of heterogeneous systems (encompasses dedicated radio layers, networks, middleware, and specialised simulation and verification tools) and which also offer consistent mechanisms with which to configure, deploy, and dynamically reconfigure both system and application level software. The EU-funded RUNES (Reconfigurable, Ubiquitous, Networked Embedded Systems) approach is based on a small and efficient ‘middleware kernel’ which supports highly modularised and customisable component-based middleware services that can be tailored for specific embedded environments, and are runtime reconfigurable to support adaptability. These services are primarily communications-related but also address a range of other concerns including service discovery and logical mobility. Framework for adaptation through reconfiguration of components eDIANA: GA no.: 100012 D2.2-C The middleware provision comprises two distinct and orthogonal parts: • first, a foundation layer – called the middleware kernel – which is the runtime realisation of a simple but well-defined software component model; • second, on top of the middleware kernel, a layer of component frameworks that offer a configurable and extensible set of middleware and application services. In this two-layer architecture, the software infrastructure for a specific heterogeneous, embedded networked system is achieved by providing an appropriate implementation or implementations of the middleware kernel, and of the required configuration of middleware (or application) services running on top of it.
