The objective is to contribute to the specification and implementation of event managers. Event based systems are particularly well adapted for programming large scale distributed applications because they enable asynchronous and anonymous communication to support interoperation and collaboration among autonomous and heterogeneous components. Events generated by producers such as wireless sensors and RFID readers are not significant enough for consumers. They must be filtered, combined or aggregated to produce more meaningful information. This project proposes an approach for composing events by querying distributed histories according to different strategies. The research is organised in three research lines: (i) definition of an event composition mechanism; (ii) specification of an event composition framework based on the Fractal model and its implementation. The approach was implemented on top of the middleware composite probes. The architecture of a probe was extended with components able to mediate events composition and aggregation
