Analysis of a hierarchical cellular system with integrated services model

RSVP (resource reservation protocol) is an attempt to provide a real-time service through the use of virtual circuits in the Internet. It is designed for the integrated services (IntServ) model, and allows Internet real-time applications to reserve resources before they start transmitting data. We consider a cellular system with two-level hierarchy, where RSVP resource reservation is made newly over the two-hop link between the macro-level base station and the mobile host during a handoff. For wireless access networks, we propose a dynamic resource allocation scheme that adapts to variations in handoff attempts, where a macrocell provides bandwidth channels for the GS (guarantee service) handoff flows overflowing from the underlying micro-cells. We derive the average system time of BE (best effort) flows. We also obtain the forced termination probability of GS flow and other performance measures.
