Fusion Network Topology

Reference work entry

The network architecture including sensors, communication channels, and fusion processing. The fusion processing may be distributed due to physical constraints in the system. If a communication channel between two sensors is long, it may be beneficial to fuse all the sensors at one end of the channel so that only the single fused decision is sent through the channel. The topology is directly impacted by the physical layout of the sensor network.
