The majority of existing papers about spectrum sensing have the assumption that secondary users (SUs) are stationary. However, mobility is an essential feature of mobile communications networks. In this paper, the detection performance of spectrum sensing by mobile SUs was analyzed. Three performance metrics, i.e., detection probability, miss detection probability and false alarm probability, were...
Abstract-An overwhelming majority of the existing work on spectrum sensing assumes that secondary users (SUs) are stationary. However, mobility is an essential property of wireless networks. In this paper, we analyze the performance of spectrum sensing by mobile SUs. Four performance metrics, i.e. detection, miss detection, false alarm and error probabilities, are thoroughly investigated. A critical...
Abstract-An overwhelming majority of existing work on soft-decision cooperative spectrum sensing makes the assumption that secondary users (SUs) in cognitive radio networks (CRNs) are stationary. Considering that mobility is an essential property of wireless networks, we analyze the detection performance of soft-decision sensing by mobile SUs. Then, a data fusion rule is proposed aiming at mobile...
In non-dedicated cooperative relay networks, each node is autonomous and selfish in nature, and thus, spontaneous cooperation among nodes is challenged. A pricing-based cooperation bandwidth allocations (CBAs) algorithm using non-cooperative game is proposed to stimulate the selfish node to cooperate. Firstly, we theoretically analyze the feasible region of charge price and reimbursement price by...
