Sensing methods in wireless systems employing opportunistic spectrum access

摘要

Can the wireless node, exchange information with the adjacent nodes in the radio system which the wireless node contacts mutually. In addition, to communicate by transferring the data over the multiple hops it is possible the node where outside of the range of direct communication leaves. The wireless node adaptation, in order at least to run sensing of one radio resource. According to one execution configuration, the node can adaptation, in order to synthesize the measurement data of sensing to the sensing result such as estimator of the probability, whether or not (is not limitation but) the resource has been less crowded of. Sensing it is run inside the node, one other wireless node, is transmitted at least especially to the multiple wireless nodes. As for each wireless node, therefore, it is possible at least to access the sensing information from one which is located around the particular wireless node other wireless node. At least, as for the wireless node, it is possible one other node, especially on the basis of the joint information from the multiple wireless nodes, to do the decision which whether or not the radio resource of specification has been less crowded for using of, is improved.
