Abstract

Cognitive Wireless Ad-Hoc Networks use cooperation in order to accurately sense the spectrum. However, the space diversity provided by the cooperative sensing is only efficient when the cooperative users are selected appropriately. This paper proposes a distributed mechanism that allows each Secondary User to decide what channels are suitable to be sensed while reducing the sensing overhead.
