Abstract

To improve data accessibility in ad hoc networks, 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.
