A stable storage in MANET: Replication or distributed storage

摘要

The notion of stable storage is very important in the area of fault tolerance. We are interested in the implementation of the concept of stable storage in mobile ad hoc environment. In this paper, we present the design and comparison of two solutions for implementing stable storage in mobile ad hoc networks (MANET) environment. One is based on the principle of data replication and the other on the distribution of the stable storage of a node on several nodes by inspiring of the technique of RAID systems used in hard disks. We exploit the creation of a structure in the form of a virtual tree in both contributions. A comparative study was performed between the two solutions through simulations in NS environment.
