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.

稳定存储的概念在容错领域非常重要。我们对在移动自组织环境中实现稳定存储的概念感兴趣。在本文中，我们介绍了在移动自组织网络（MANET）环境中实现稳定存储的两种解决方案的设计和比较。一种是基于数据复制的原理，另一种是通过启发硬盘中使用的RAID系统技术，将一个节点的稳定存储分布在多个节点上。我们在这两个贡献中都以虚拟树的形式利用了结构的创建。通过在NS环境中进行仿真，对两种解决方案进行了比较研究。
