Research on the Shortest Path First of Data-Centric Storage

This paper analyses three existing methods of WSN data storage. Based on disadvantage of Data-Centric Storage(DCS), the Shortest Path First of DCS(SPF-DCS) is present. Compared to DCS, the advantage of this method is that home node finds only one node as its own replica node. SPF-DCS can reduce communication between home node and other nodes, decrease the power consumption of node and prolong lifetime of WSN.
