Abstract
Abstract A mobile system capable of proactively predicting characteristics for optimal communication among mobile nodes comprises a network controller and adaptive predictive mobile nodes. The adaptive predictive mobile nodes contain a position location technology element, a database containing information on factors affecting radio propagation, and a prediction processor. To provide energy efficient power control and routing for a communication, the adaptive predictive mobile node determines its current and predicted future position and the current and future predicted positions of other nodes in the network. Based on the information obtained, the adaptive predictive node executes a set of prediction capabilities in the prediction processor. After executing these capabilities, the adaptive predictive node identifies the advantaged location, power level, transmission parameters, communication time and route for communications between nodes. The adaptive predictive mobile node can then communicate when the criteria are met or may request scheduling for the communication based on the criteria. To request scheduling, the adaptive predictive node communicates the identified criteria to the network control entity. The network control entity determines whether the request can be supported. If the network can support the request, the communication is scheduled. If the network cannot support the request, the adaptive predictive node has the option of recalculating the criteria for communication and requesting scheduling based on the alternative criteria.
