Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Distributed storage systems introduce redundancy to protect data from node failures. After a storage node fails, the lost data should be regenerated at a replacement storage node as soon as possible to maintain the same level of redundancy. Minimizing such a regeneration time is critical to the reliability of distributed storage systems. Existing work commits to reduce the regeneration time by either minimizing the regenerating traffic, or adjusting the regenerating traffic patterns, whereas nodes participating the regeneration are generally assumed to be given beforehand. Hover, real-world distributed storage systems usually exhibit heterogeneous link capacities, and the regeneration time is highly related to the selection of the participating nodes. ,  consider the minimization of the regeneration time by selecting the participating nodes in heterogeneous networks.  propose optimal node selection algorithms respectively for two cases: 1) the newcomer is not given, 2) both the newcomer and the providers are not given. Analysis shows that the optimal regeneration time can be achieved in each case.  then consider the effect of flexible amount of data blocks from each provider on the regeneration time, and apply this observation to enhance our schemes. Experiment results show that our node selection schemes can significantly reduce the regeneration time, especially in practical networks with heterogeneous link capacities, compared with the scheme based on random node selection.
