Two-Tier CHORD for Decentralized Location Management
To conceive the full potential of ubiquitous mobile computing, mobile nodes must be able to roam seamlessly across different networks. However, the location i.e. IP address, of a called mobile nodes must be determined within a certain amount of time, before the services are blocked. With the upcoming 3G, 4G and wireless LAN technologies, it is necessary to have an efficient location management system that adapts to such dynamic environments, and augment problems like center point of failure, delay and lack of reliability. One approach is to provide decentralized location management, using CHORD, whose key vale mapping can efficiently determine the required name to IP mapping.
