When Pennsylvania faced similar problems, the state approved slot machines at the racetracks and constructed a model for the distribution of slot revenues that is enviable.
But knowledge that the distribution of slot machines was often controlled by organized crime led to increasing legislation restricting their sale and transportation as well as their use except in private social clubs.
In addition, Li et al. [5] have pointed out that very little research has been done on the probability distribution of slot selection.
One interesting finding of the simulation experiment is that the distribution of awake slots in a schedule affects the delay performance the more evenly the awake slots of receivers are distributed, the more opportunities for transmission the sender can have, especially when the link qualities are relatively high.
Alternatively, dripping can be realized by means of a periodic distribution of porous slots.
Further, it is worth to note that for each sensor, the evenness of the distribution of scheduled slots takes effect on the packet collection delay.
The model confirmed that the distribution of the slots in the underdrain was a critical factor for determining the length of the region with a non-uniform flow within the sand.
The working process of set-up phase needs to complete the movement of mobile agent node, the establishment of routes, and the distribution of time-slot allocation.
The sorting sheet had nine categories (1 extreme dis-priority, 5 non-priority, 9 extreme priority) with symmetrically distributed number of slots under each category: categories 1 and 9, 3 slots each, categories 2 and 8, 4 slots each, categories 3 and 7, 6 slots each, and categories 4, 5, and 6, 7 slots each (Additional file 1, Sorting Sheet & Instructions).
The evenness of the distribution of scheduled time slots for each sensor, in particular the second moment of scheduling intervals, affects the mean packet transmission delay, which will be proved in Section 4.1.2.
