This paper addresses the issue of defining a location service suitable for very dynamic and highly populated networks (millions of users), where services might experience highly correlated peaks of traffic or synchronized access to specific servers. Mobile agent technology is flexible enough to solve the major problems, allowing the dynamic deployment of new application servers when needed. But it requires an adequate location service to increase client adaptability. This paper describes a very dynamic location service that can adapt both to server and client needs and to the load on the system. Sets of simulations were performed to study the effect of the location network structure on the load distribution.
