8.4.4 Data fusion
Architectures
Figures 8.11 and 8.12 illustrate the two main architectures for a decentralised distributed detection system – the serial and parallel configurations. We assume that there are L sensors. The observations at each sensor are denoted by yi and the decision at each sensor by ui; i D 1; : : : ; L, where
ui D | ²1 0 | |
---|---|---|
The parallel system has been widely considered and is shown in Figure 8.12. Each sensor receives a local observation yi, i D 1; : : : ; L, and produces a local decision ui which is sent to the fusion centre. At the fusion centre all the local decisions ui, i D 1; : : : ; L, are combined to obtain a global decision u0. The parallel architecture is
