This master thesis deals with the involved aspects for the creation of a framework for connectivity in JAMP (Java Architecture for Media Processing). The conception of this framework aims to make possible the use of mobile devices by means of other wireless network technologies. Such technologies, as Bluetooth, used for the publication/localization of services registered in the JBroker, the broker of JAMP Platform developed in Java/RMI, as well as the communication of devices that make use of such technologies through this broker, had been used in the implementation and tests of the framework developed. The implementation aims to access, from devices with Bluetooth network interface, the available remote services in the Internet. These services are requested by mobile devices, such as PDAs, cellular or smartphones, that they consult access points, in Bluetooth communication. The access points consult the JBroker that returns a reference for the service to be consumed. The access points then direct the result to the mobile devices. The experiments developed in this work had been based on scenes where a mobile device, in Bluetooth communication, requests services to a point of access in a PC and this, saw TCP/IP, invokes remote methods in the servers who disponibilizam the services, saw Java/RMI. JAMP already all presented the mechanism of localization of services saw Java/RMI, however it did not present the extension developed with this work, where they had been created one proxy, that it is executed in the access point, and the use of services of the JAMP to break mobile devices that if communicate through technology of different net of TCP/IP. Being thus, its innovation is in the capacity of use of devices that make use of technology of Bluetooth net, being able to be extended to other technologies, without needing would reengeneering previously existing in the architecture.
