Coordination of silent periods for dynamic spectrum manager (dsm)

Abstract

A method for use in a Dynamic Spectrum Manager (DSM) for coordinating asynchronous silent periods in a network, the method comprising detecting a primary user in the network, transmitting a Silent Period Start Control Message to one or more cognitive radio (CR) nodes in the network, wherein the message indicates the start and duration of a silent period and initiates spectrum sensing, receiving a Measurement Report Control Message from the one or more CR nodes in the network indicating results of spectrum sensing, and transmitting a message to the one or more CR nodes, wherein the message instructs the one or more CR nodes to move to a different frequency based on the spectrum sensing results.

         15 . A method for coordinating asynchronous silent periods in a network, the method comprising:
 determining a time-to-trigger (TTT) period for triggering asynchronous sensing events;   sending the TTT period to a plurality of nodes in the network;   receiving an asynchronous sensing event report generated based on the TTT period; and   sending a silent period control message to nodes in the network.
