Simulation Scenarios. (a) Readers operating across the width of a moving belt containing tags. The readers are spaced equally apart with the width of belt deciding overlap between readers. The tags are uniformly distributed across the width of the belt. (b) Multiple cells with a reader assigned to the center of each cell. Each group of tags in a cell could be visualized as those on a mobile object, say a box or truck, that is replaced by another and so on. The number of tags in a cell has a geometric distribution starting from Cell 1. The tags in each cell are uniformly distributed.
