Anchor-Node-Based Distributed Localization with Error Correction in Wireless Sensor Networks
Published 2012-04-01“…If correction needs, the initial position is repositioned using hop progress by the information of anchor nodes located several hops away so that error propagation is reduced (REP); the hop progress is an estimated hop distance using probability based on the density of sensor nodes. …”

Research on Transmission Capacity Characteristics of the Cluster Flight Spacecraft Network
Published 2021-01-01“…By simulating the transmission capacity of decode-and-forward, the transmission capacity characteristics of a single hop and dual hops are analyzed. The simulation results showed that transmission capacity performance changes with the change of the time slot in the orbital hyperperiod, and the transmission capacity of a dual-hop relay has better performance than a single-hop transmission in the cluster flight spacecraft network.…”
