Abstract

We have proposed an efficient layered-data delivery system through multiple heterogeneous networks, which are on-demand and broadcast [1]. It is considered that layered data, such as map data, are composed of (1) common parts available or useful to many clients, and (2) personalized parts for individual clients. The system sends the personalized parts through on-demand networks and the common parts through broadcast networks. In this paper, we implement and evaluate a performance model of the system consisting of a client and two servers (broadcast and on-demand). The evaluation results show that our proposed system works effectively under certain conditions.
