In an embodiment, a method of managing distributed storage in a wireless network is disclosed. The wireless network comprises a plurality of data generating nodes, each data generating node configured to generate and store data symbols and parity symbols. The parity symbols depend on data symbols stored on other data generating nodes. The method comprises receiving indications of link quality estimates for wireless links between the data generating nodes; selecting an arrangement of an array code from a plurality of possible arrangements using the indications of link quality estimates, the array code depending on the number of data generating nodes in the plurality of data generating nodes and a required number of nodes from which all of the data symbols stored in the wireless network can be generated, the arrangement indicating for each data generating node, the dependence of the parity symbols stored on that data generating node on the data symbols stored on other data generating nodes; and sending an indication of the selected arrangement to the data generating nodes.
