This paper presents mechanisms for the dynamic management of the content of several Universal Description, Discovery, and Integration (UDDI) registries. These mechanisms are deployed in the context of a wireless environment of Web services. By content, it is meant the announcements of Web services that providers submit to a UDDI registry. Unlike other initiatives in the Web services domain that consider a single UDDI registry and a wired communication infrastructure, this paper is concerned with the fact that: several UDDI registries are deployed, there is no wired communication infrastructure between the UDDI registries, and absence of a centralized component for coordinating the UDDI-registries. The solution presented integrates users and software agents into what we call messengers. Initially, software agents reside in users' mobile devices and cache a description of the Web services that satisfy their users' needs. Each time a user is in the vicinity of a UDDI registry, her software agent interacts with that registry, so the details stored on Web services are submitted. © Springer Science+Business Media, LLC 2007.
