US 7,254,389 B2 · Wireless link simulation with generic caching

Abstract

A simulation system includes a cache structure that stores determined characteristics related to the propagation of an event. If a similar event occurs, and the factors affecting the determination of these characteristics have not changed, the characteristics associated with the new event are retrieved from the cache, rather than being re-determined from the underlying factors. In the example of mobile transceivers, if multiple transceivers share a common set of underlying factors, the determined characteristics of one transceiver can be shared among all of the other transceivers. If the underlying factors are dependent upon geographic area, mobile transceivers that enter a geographic area having associated cached characteristics can use the cached characteristics of other transceivers that are, or had been, in the area. Because the cache process is structured to intercept a call to the routine that determines the characteristics, the modifications to a simulation system to incorporate this caching feature should be minimal.

Dependent claims

A simulation system comprising:

an event handler that is configured to determine occurrences of events,
a node simulator that is configured to simulate each event to determine one or more characteristics associated with the occurrence of the event,
a cache that is configured to store the one or more characteristics associated with the occurrence of select events, and
a cache controller that is configured to determine whether:
to invoke the node simulator to determine the one or more characteristics associated with a subsequent event or
to retrieve the one or more characteristics associated with the subsequent event from the cache.
