Abstract
In a heterogenous networking environment, a new practical distributed storage model is defined by introducing the concepts of repair topology and retrieval sets. How to repair a failed storage node so as to minimize the system repair cost is investigated. It is shown that the repair cost minimization problem can be decomposed into a combinatorial problem and an integer linear programming problem. Moreover, a heuristic algorithm to find suboptimal repair topologies is given.
