Palma : A P 2 P based Architecture for Location Management

To realize the potential of ubiquitous mobile computing, keeping track of mobile application users becomes more important. In wireless mobile networks, in order to effectively deliver a service to a mobile user, the location of a called mobile node must be determined within a certain time limit before the service is blocked. With the upcoming 3G, 4G and wireless LAN technologies, it’s necessary to have an efficient location management system that adapts to such dynamic environments. In this paper, we propose a highly scalable, self-organizing P2P based architecture for location management; namely PALMA. The performance of the proposed scheme was evaluated through a prototype implementation.
