Methods and systems for adaptive cross-layer cross-node optimization in wireless communication systems are provided. Adaptive cross-layer cross-node optimization allows for conventional cross-layer optimization coupled with the ability to adaptively optimize cross-layer interactions across node boundaries. In one aspect, adaptive cross-layer cross-node optimization includes adaptively and dynamically shifting functions/layers among nodes in a network, so that a global network objective is achieved. In another aspect, adaptive cross-layer cross-node optimization includes adaptively and dynamically distributing functions/layers across a network, according to changes and/or events in the network. In a further aspect, adaptive cross-layer cross-node optimization includes dynamically defining or changing individual node functions within a network, so that a global network functionality may emerge.

Systems of and methods for providing cellular priority access and topological guidance information to cellular users are described, employing wireless ad hoc network and cellular logic. A centralized aspect of acquiring cell loading information and geographic coordinates is combine with a distributed scatternet forming aspect to enable guidance information to be computed and indicated to the user. The guidance information is reflective of cell loading and congestion status of neighboring cells, as well as the availability of alternative radio resources in the user's current cell or neighboring cells. The system may also be employed in redistributing cell traffic among cells to optimally balance cell loads.

This disclosure relates to a communications network including a base station and two or more distributed cells which are remote from the base station. The cells are coupled to the base station by transmission mediums which may, for example, be cable, fiber, and/or air. Between the base station and each cell, there is a time delay or transmission time, between the time when a communication that is received at one of the two is transmitted to and is received by the other of the two. The time delays of the two cells are unique or distinct one from the other. The network includes a time responsive system which is responsive to the time delay for a communication between the base station and one of the cells. Since the time delays are distinctive, the time responsive system identifies the cell associated with the communication. The time delays of the cells may be inherent in the circuitry and transmission mediums between the base station and the cells. A time delay element also may be provided to modify the time delay of one or more of the cells, if the inherent time delays are not sufficiently distinct.
