In ad hoc networks, data accessibility decreases due to network divisions. To solve this problem, it is effective that each mobile host creates replicas of data items held by others. In this paper, we assume an environment where mobility and access characteristics of mobile hosts have the locality and propose a method that locally relocates replicas just before a network division occurs.
