Spatial correlation data forwarding scheme for cyber-physical systems
信息物理系统基于空间相关性的数据传输

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.
