N2 - In this paper, we propose a novel repairable fountain codes (RFC) used in D2D data storage systems for failure data recovery. This RFC has the priority of unequal repairing locality (URL), which can provide unequal data protection for different nodes’ bandwidth and power in different areas. The lower locality of URL-RFC can reduce the repair bandwidth in D2D storage system, and tradeoff different nodes’ capabilities of transmitting. We firstly give the heterogeneous D2D storage network model, and analysis the communication cost for data download and node repair. Then, the construction method of URL-RFC is given based on generated matrix. Simulation results show that, URL-RFC significant outperforms conventional distributed codes on communication cost in heterogeneous D2D storage system.
