Abstract

The authors have proposed a music delivery system JAMS (JAMais vu System), which uses ad-hoc networks with mobile devices for the localization services. In this paper, they focus on a cache management scheme for JAMS to deliver music files efficiently. The proposed scheme makes it possible to manage cache files robustly by using adaptive cache delivery according to each node request. In addition, the authors conduct a simulation experiment and obtain access failure ratio of music files under various system conditions. The simulation results indicate that the proposed scheme is suitable for the system using localization services.
