Before revision:  Moreover, we show that when the locations of users and resources are modeled by statistical point processes,  the spatial system under unidirectional policies can be mapped to a temporal queuing system , thus allowing the application of a plethora of queuing theory results that yield closed form expressions.
After revision:  Moreover, we show that when the locations of users and resources are modeled by statistical point processes, and resources are allowed to satisfy more than one user, the spatial system under unidirectional policies can be mapped to a temporal queuing system , thus allowing the application of a plethora of queuing theory results that yield closed form expressions.
