Handoff decision in multi-service networks

Abstract

The fourth generation of telecommunication networks will be a mix of existing and emerging wireless and wired networks. They will provide a framework for multi-service usage cases, such as Internet access, geolocation and real-time applications (such as voice and video). In this paper we refer this collection of interoperating networks as multi-service networks and elaborate the aspects of system architecture and mobility management in this heterogeneous environment. First, requirements for system architecture are outlined. A novel multi-service architecture is defined based on fully integration of location based services and IP mobility approach. Handoff decision policies for multi-service network scenarios are then considered and simulation results for the handoff algorithm are presented. The suitability of the fuzzy logic algorithm is discussed in this context.
