Abstract

In mobile ad hoc networks, partitioning occurs frequently. Data replication techniques are used to improve data accessibility but require data consistency to be maintained in case of update. In this paper, we propose hybrid push-pull data update propagation. The idea is to divide replica holders into SH(Push) and LL(Pull) categories. Updates are pushed to SH nodes whenever they occur. LL nodes pull the updates from SH nodes in a frequency suitable for their needs. The novelty of this method that it minimizes communication cost when saving an adapted level -to mobile hosts needs- for data consistency.
