OW2 Projects Organized by Maturity

Key features of MobIoT lie in: I. the exploitation of ontologies to overcome the heterogeneity of the Things network, II. the introduction of probabilistic approaches for both registering and retrieving networked Things so as to be scalable and support millions, even billions, of them, and finally, ( III ) the exploitation of Thing services composition to better satisfy user queries for real-world information, while wrapping the complex interactions with the dynamic environment internally.

MobIoT is implemented using Java and the Android platform, and consists of two complementary components: The MobIoT Mobile middleware and the MobIoT Web Service. The MobIoT Mobile middleware is deployed on mobile devices (e.g., smartphones, tablets, sensor devices). It includes ( I ) the Query component that enables the querying of the physical world, II. the Registration component that deals with the probabilistic registration of local sensors and actuators, III. the domain ontology that allows reasoning about the features of Things, and ( IV ) the Sensor Access component that enables the sensor data retrieval and exposure. The MobIoT Web Service consists of ( I ) the Registry component that keeps track of the registered services, ( II ) the probabilistic Lookup component that enables scalable service retrieval, ( III ) the Composition & Estimation component to answer queries over the physical world by taking into account both the available Thing services and the relevant to the domain and devices ontologies.

MobIoT is developed in the context of the FISSi initiative and is based on the results of the CHOReOS project. The project will take advantage of the OW2's forge for hosting and exposing the project's code and documentation and the bug tracker for supporting the development's needs.

Given the fact that we are moving towards a world where everything is connected, the iConnect project targets to provide a universal solution towards interoperability between highly heterogeneous systems by reconciling behavioral discrepancies, from the application down to the middleware layer. To achieve this, iConnect introduces at the application layer, tools for abstracting and semantically annotating the functionality of systems so as to enable the discovery and coordination with other relevant ones. Then, at the middleware layer, complementary tools are responsible for translating messages that are transmitted between systems that implement heterogeneous interaction paradigms or communication protocols.

Key features of iConnect include:

Introduction of enablers for universal discovery of resources, composing legacy discovery protocols 2. Synthesis and deployment of mediators specified as enhanced labeled transition systems towards allowing networked systems that have compatible functionalities to interact despite mismatching interfaces and/or behaviors 3. Cross-paradigm and cross-protocol interoperability with the use of the XSB (eXtensible Service Bus) and the LSB (Light Service Bus) middleware components

iConnect is developed in the context of the FISSi initiative and is based on the outcomes of the CONNECT and CHOReOS FP7 projects. The project will take advantage of the OW2's forge for hosting and exposing the project's code and documentation along with the bug tracker and mailing lists for supporting the development's needs.
