Title:
The space-time random voting system for a cognitive network
Document Type and Number:
Japanese Patent JP6165463
Kind Code:
B2
Abstract:
Sensing device for providing frequency spectrum usage information to a collection center for a cognitive wireless network. A message is received from the cognitive wireless network to collect frequency spectrum usage information at a defined time slot for a particular frequency spectrum band. The sensing device collects frequency spectrum usage information at the indicated time slot by scanning the particular spectrum band to determine whether a signal energy above a particular threshold is detected. The sensing device obtains a geographical position for the sensing device. A sensing report is then generated that includes at least one of the frequency spectrum usage information and the geographical position. The sensing report is then sent to the collection center.
Subsequently, the sensing device may receive a transmission from the cognitive wireless network on the frequency spectrum band if the collection center determines that the frequency spectrum band is unused.
