| Abstract(in English) | In ad hoc networks, a collection of mobile hosts dynamically form a temporary network without using any existing network infrastructure or centralized administration. Since disconnection occure frequently, data accessibility in ad hoc networks is usually lower than that in the conventional fixed networks. To improve the data accessibility, we have proposed a few methods of replicating data items on mobile hosts by considering the data access frequencies from mobile hosts to each data item and the network topology. In this paper, we consider the stability of radio links among mobile hosts to enhance our previously proposed methods. We show that the newly proposed methods are more efficient by simulation results. |
