In this paper, the data storage problem in Unattended Wireless Sensor Network (UWSN) is explored. Different form ordinary Wireless Sensor Network (WSN), UWSN is usually deployed in extremely harsh environment and the Sink node (data collector node) is not always in the network. Before Sink node appears, in order to ensure the reliability of sensed data against node failure, every sensed data packet must be stored in the network distributed. To improve the data storage reliability in unattended wireless sensor networks consisted of n sensor nodes, a new kind of distributed storage algorithm based on directional random walk with length cn, c > 1 is proposed.
