Abstract:
1. A system for efficient routing in a multiple hop wireless communication network comprising a plurality of infrastructure nodes, the system comprising: link monitoring circuitry for acquiring link quality information indicating link status between said infrastructure nodes; electronic processing circuitry for using said link quality information to determine a route path through the infrastructure nodes using a predictive procedure; said link quality information containing time varying information of said link status including radio channel information given by measurement of at least one of Doppler spread, coherence time, average fading duration, signal strength, or signal to interference noise ratio; and said predictive procedure being configured to use said time varying information to provide multiple calculated anticipation scenarios anticipating a near-future link status based on at least a fading parameter that indicates one of a slow fading category and a fast fading category, with the predictive procedure being configured to analyze the anticipation scenarios to determine the route path including using the link quality information in a comparison with determined routing anticipation criteria; and a router for routing data packets according to the determined route path.
