This paper proposed a novel data gathering and forwarding scheme named spatial correlation data forwarding(SCDF).SCDF introduced a small overhead to gain the relative distance from a node to a sink node and then to calculate the node forwarding probability,which gave a guidance to message transmission based on spatial correlation between nodes.Simulation results show that SCDF does not only achieve a relatively low data forwarding energy consumption,but also get the higher message forwarding ratio with lower transmission overhead and data forwarding delay than direct delivery(DD) and Epidemic algorithms.
