Abstract(in English) In this paper, we propose two updated data dissemination methods to update old replicas effectively in ad hoc networks where each data item is updated at inconsistent intervals. In the first method, when a mobile host holding an original data item updates the data item, it disseminates the uodated data item to all connected mobile hosts. In the other method, when two mobile hosts are connected, they re-disseminate updated data items. Our proposed methods reduce the number of accesses to invalid old replicas and improve data accessibility.
