Abstract:
1. A method of power management in a wireless ad hoc network, said network including a plurality of nodes, and said method comprising: monitoring a current traffic load of said wireless ad hoc network, wherein said current traffic load is a first traffic load determined at a first instant in time; in response to said first traffic load, selecting a first subset of epochs within a time window of epochs for network communication; communicating a message between said nodes in said network, said message identifying said first subset of epochs as being allowable for use in communicating network traffic; following receipt of said message, said each of said nodes modifying a transmit capability mode by entering a run state to enable communication of said network traffic over said network during said epochs within said first subset of epochs and by entering an idle state during remaining ones of said epochs within said time window; detecting a second current traffic load at a second instant in time following said first instant in time; adjusting said first subset of epochs to form a second subset of epochs within said time window in response to said second current traffic load; communicating a second message between said nodes in said network, said second message identifying said second subset of epochs as being allowable for use in communicating said network traffic; and following receipt of said second message, said each of said nodes modifying said transmit capability mode by entering said run state to enable communication of said network traffic during said epochs within said second subset of epochs and by entering said idle state during said remaining ones of said epochs within said time window.
