Abstract
A method is provided which enables the connection of nodes out of communication range while minimizing the energy consumption in standby nodes. Specifically, the present invention provides a method to control the wake up rate of standby nodes in a multi-hop communication system. An access point collects, processes, and refines statistical information regarding one or more system parameters; determines a wake up rate based on the statistical information and one or more historical information; and transmits the wake up rate to nodes in its coverage area. A node receives the wake up rate; and periodically changes from a sleep state to a wake up state at the wake up rate to support routing functions for providing multi-hop communication to the one or more access points.
