ABSTRACT:
Future wireless networks will be integrated with existing wired networks. Together, this environment will compose a multimedia network infrastructure, providing advanced data, voice, and video services, which is referred to here as InfoCity . In this chapter, several emerging technologies, which might be used to provide the mobile multimedia services needed in the event of such a technology integration and convergence are presented. Careful consideration is given as to how these new technologies could best be used to offer a state-of-the-art, networked InfoCity , as a solution for next generation distributed multimedia applications. InfoCity, as presented here, is envisioned as a wired and wireless co-existence environment, with seamless service delivery of full multimedia applications, regardless of the user s location and receiving device. Frame relay and ATM are presented as facilitating high-speed connections to a future broadband architecture. In order to support the diverse service needs of multimedia, Quality of Service (QoS) must be assured. Resource reservation protocol (RSVP) is considered as an example of the type of service-arbitration technique which could be used to provide users with such QoS assurance based on user need, rather than fair allocation. Finally, mobile IP is included as one approach to providing mobile host support in this new environment.
