A Gossip Protocol to Support Service Discovery With Heterogeneous Ontologies in MANETs

Service discovery in Mobile Ad hoc NETworks (MANETs) is an integral part for collective application interoperability. The discovery process must cope not only with transient communication but also with an environment where autonomous mobile nodes act as both service providers and consumers. Imposing predefined service interfaces in such an unpredictable and dynamic environment is an inappropriate assumption. A more flexible description and discovery mechanism can be provided with the use of ontologies and semantic reasoning. Assuming that services are described by heterogeneous ontologies poses many technical challenges but is more realistic than requiring single domain ontology.
