Searching continuous nearest neighbors in road networks on the air
作者:
Highlights:
• We take the first step toward processing Continuous Nearest Neighbor queries in road Networks under wireless data Broadcast environments (CN3B).
• We present an efficient approach, called NVD quad partition, to partition the NVD structure of the underlying network into grid cells.
• A distributed index, called NVD-DI, is proposed to support CN3B query processing.
• Simulation experiments reveal the efficiency of our CN3B method and the associated NVD-DI index.
