| Abstract(in English) | Recently, spectrum sharing with cognitive radio for wireless vehicular networks (WVN) has been emerging. For achieving spectrum sharing, spectrum sensing is used to protect primary user (PU) communications. However, simple sensing is affected by variable surrounding environment caused by mobility of secondary users (SU). The performance degrades in low signal to noise ratio (SNR) environment. Therefore, a cooperative sensing improving performance has been studied. In the cooperative sensing, since many costs such as power and wireless resources need to share observed information, setting appropriate sensing parameters is important to reduce costs. In order to realize resource efficient sensing, an adaptive parameter control scheme for cooperative sensing based on a measurement-based spectrum database is proposed in this paper. In this scheme, firstly secondary user gets location information and sends it to the database. The database searches the averaged received power information of PU signal at the location SU and reports it to the SU. The SU can estimate the PU detection performance according to parameters such as presence or absence of cooperation, the number of cooperation nodes and so on based on the information from database. SU decides sensing parameters to fulfill the desired criterion values such as detection probability and false alarm rate. As a result, the proposed scheme ensures the desired performance with minimum costs on a mobile environment such as WVN and the stable communication performance of PU can be protected. |
