Abstract

Method and apparatus for scheduling transmissions in a wireless communication system using historical information and usage patterns of remote users in the system. Usage patterns for users within a system are stored and analyzed to optimize transmissions and resources in the system. In one embodiment, the user patterns are used to predict travel routes and transmissions scheduled accordingly. In another embodiment, the system is an ad-hoc system or a hybrid system, wherein the usage patterns are used to determine the source-to-destination paths.
