Abstract

This paper proposes a new hierarchical location update and routing scheme for wide area mobile computing environment. the scheme aims to be well scalable to network hierarchy. It achieves fewer location updates by limiting location updates to a designated set of redirection agents at border of patron areas, from where the communication requests are most often generated. With benefit of the hierarchical redirection concept, there is no need to notify a host's movement within the patron area to the source hosts outside this area. Despite of lightweight location update, the scheme provides nearly optimal routing for most communications bypassing the mobile host's home network. The proposed scheme was compared and analyzed with the other schemes in the location update overhead and routing efficiency point of view.
