| Figure above illustrates how a scoped tuple is propagated through the TOTAM network. It depicts two types of locations, the blue and red locations corresponding to two teams of a multi-player game scenario where users (blue team) can use their PDA’s to chase dangerous (virtual) gangsters (red team) in the outdoors. The scope of the propagated tuple has been limited to blue locations. Figure (a) illustrates that a tuple is injected from the location with a star. This location is connected to four blue locations and one red location. As the scope of the tuple is limited to blue locations the tuple is only sent to the four blue locations. From those four locations the tuple is transitively propagated obeying the scope of the tuple until all connected blue locations are reached without being transmitted to a red location. Note that one blue location is not transitively connected to the sending device and thus does not receive the tuple. Figure (b) illustrates that a blue location moved into the range of the isolated blue location and thus, transmits the tuple to it. Again the tuple is not transmitted to nearby red locations. It is important to note from this operational sketch that the first isolated location receives a tuple without being connected at any time with the start location in which the tuple was originally inserted. | Figure above illustrates how a scoped tuple is propagated through the TOTAM network.
