Performance analysis of distributed location management for wireless networks

Location management is an essential process in future mobile communication networks. An important issue is that of efficient management of the location database. The next generation mobile communication network is proposed to integrate with a TINA-compliant architecture enabling one to handle that kind of mobile-specific processes. This paper discusses the design and modeling of a distributed location management based on a TINA-compliant architecture for wireless mobile communication networks. We consider a distributed location database architecture for location management, performing two strategies: HLD (home location database) and HLD-CLD (HLD with a cache location database). The local cache CLD is used to reduce signaling traffic in the network and to accelerate database searching and updating. This paper also presents a simple methodology for evaluating some basic location management algorithms for a distributed location database based on a TINA-compliant architecture for wireless communication networks.
