Abstract

To improve data accessibility in ad hoc networks, wehave proposed a few methods of replicating data items onmobile hosts by considering the data access frequenciesfrom mobile hosts to each data item and the network topology.In this paper, we consider the stability of radio linksamong mobile hosts to enhance our previously proposedmethods. We show that the newly proposed methods aremore efficient by simulation results.
