Abstract

In this article we propose a distributed data replication algorithm to be used for data sharing in Mobile Ad hoc NETworks (MANETs). Our system replicates data before users access them. To this purpose, it uses a predictive algorithm based on semantic information about the user and the data and previous access patterns. It also aims at creating enough replica to prevent data loss in case a peer unexpectedly disappears or a partition occurs. To this end, we also propose a stable group creation algorithm based on long lasting connectivity. While data sharing systems for MANET already exist, both the use of semantic information and of temporal stability are new in this domain. We illustrate the interest of the proposed algorithms by showing how a wiki service on MANETs would benefit from them.
