    A MOF-based Social Web Services Description Metamodel
    (CERIST, 2015-12-09) Benna, Amel; Maamar, Zakaria; Ahmed-Nacer, Mohamed
    To make IT community adopt social Web services, both social Web service-based applications and their support platforms should evolve independently from each other while sharing a common model that represent the characteristics of these social Web services. This paper proposes a model-driven approach that achieves this duality. First, the approach identifies a social Web service's properties. Then a Meta-Object-Facility(MOF)-based social Web services description metamodel is developed. A prototype illustrates how the proposed MOF-based metamodel is used.

    Enabling ad-hoc collaboration between mobile users in the MESSENGER project
    (Kluwer Academic Publishers-Plenum, 2007-03) Maamar, Zakaria; Mahmoud, Qusay H.; Derhab, Abdelouahid
    This paper discusses how ad-hoc collaboration boosts the operation of a set of messengers. This discussion continues the research we earlier initiated in the MESSENGER project, which develops data management mechanisms for UDDI registries of Web services using mobile users and software agents. In the current operation mode of messengers, descriptions of Web services are first, collected from UDDI registries and later, submitted to other UDDI registries. This submission mode of Web services descriptions does not foster the tremendous opportunities that both wireless technologies and mobile devices offer. When mobile devices are “close” to each other, they can form a mobile ad-hoc network that permits the exchange of data between these devices without any pre-existing communication infrastructure. By authorizing messengers to engage in ad-hoc collaboration, collecting additional descriptions of Web services from other messengers can happen, too. This has several advantages, but at the same time poses several challenges, which in fact highlight the complexity of ad-hoc networks.
