Toward Optimal Replication for Hierarchical Location Management in Wireless Systems
[chapter]
1999
Lecture Notes in Computer Science
Preserved Fulltext
The location information of users can be replicated at various databases in a hierarchy to improve the efficiency of call lookups at the expense of increase in update and storage cost. ...
In this paper, we systematically investigate this problem and propose two solutions. ...
To provide faster lookup, [4] and [15] propose to cache or replicate the location information of a user in the databases of additional zones, so that subsequent calls from these zones can reuse this ...
